The Reaction Research Society (RRS) met for our monthly meeting on March 8, 2019, at the Ken Nakaoka Community Center in Gardena, CA. The RRS was glad to welcome our newest associate member, Jaren Li. After our reading of the treasury report, we began the agenda.
[1] Preparing for the RRS symposium, Saturday, April 27, 2019
The first topic was the status of the forthcoming 2019 RRS symposium. This will be an all-day event, Saturday, April 27, 2019. Frank Miuccio, our symposium coordinator, was happy to report we have confirmed Cal Poly Pomona and Northrop Grumman as attendees. With nearly 200 Event-brite tickets sold already, we have 20 exhibitors and nearly a full roster of speakers throughout this all-day event.
The RRS will need the help of our membership for setting up on the night before. Also, we expect a good crowd on Saturday and we’ll need our membership again to help support the number of activities going on behind the scenes. The executive council will be contacting our members to enlist their support for specific tasks in the next few weeks. The one thing that everyone can do is spread the word and share our flyers with those interested in coming.

[2] Improvements to the RRS social media presence
This is to be a regular agenda topic to be led by our two media officers, Bill Janczewski and Alastair Martin. In their absence, the society discussed a few common sense things that will be helpful. Including links in our Instagram and Facebook postings back to the RRS.ORG website should help bring more people to read about us. Also, the RRS should track the number of hits our sites are getting as a way of measuring improvement.
Alastair Martin held the second podcast for “Rocket Talk Radio” at his Hollywood studio. Richard Garcia and I both were pleased to be guests on his show as we talked about the timely subject of Small Launchers. There’s been a lot of recent activity in this area with new businesses such as RocketLab, Vector Space Systems, Relativity Space and Firefly Aerospace entering the market. This project is through Alastair’s company, Production Tribe LLC. You can find Alastair’s podcast at his website at Watch Hollywood -dot- TV:
Frank Miuccio attended a seminar at the University of Southern California (USC) early this month on leadership of non-profit groups. He said he got a lot of practical advise and suggestions for improvement. He did not have his findings summarized for the March meeting, but he can elaborate on his experiences at the USC seminar at the next meeting.
[3] RRS Mission Statement
A mission statement is a short statement of purpose to describe why an organization exists. After reviewing a few drafts, the society decided to use statements made in our articles of incorporation, but it has not been posted on our website until now. The RRS mission statement can be found near the “Donate” button on the main toolbar of the RRS.ORG website.
[4] RRS Website Articles and Publication Guidelines
It was suggested that RRS ought to publish a set of guidelines for new members and contributors to the RRS.ORG website. The society encourages all of our membership to do more than simply discuss their ideas, but to put them down into writing for the wider audience to see. Our society is one of builders, thinkers and experimenters. We have a long legacy of past articles, but what is equally important is that we continue to contribute to our growing body of knowledge.
The initial set of publication guidelines for website articles was sent to our society membership a couple weeks ago. Although I have not received any formal feedback, the society decided at the March 2019 meeting that those initial publication guidelines will be published both on the RRS.ORG website and on our Facebook page. The society reserves the right to edit and holds the sole discretion to publish articles or not. However, at this time, the RRS is very interested in what kinds of things our membership would like to hear about. More importantly, the society would like our membership to contribute an article.
[5] Loyola Marymount University base11 Liquid Rocket Competition
The RRS has been working with Loyola Marymount University (LMU) in Westchester, CA, providing them with guidance on their liquid rocket vehicle design that will ultimately compete in the base11 Space Challenge. A few members of the LMU team were in attendance at the March 2019 meeting of the RRS. The goal of the competition is to be the first university group to fly a liquid rocket to an altitude of 100 km for a prize of $1,000,000 USD. A link to the base11 home page is below.
The LMU team are very busy assembling their Preliminary Design Review (PDR) submitted presentation which is due in the next few weeks. They were able to ask questions of the society members present on details relevant to their liquid rocket.

Per our charter to support academic groups and our membership, the RRS has supported other liquid rocket competitors in this competition including University of California, Los Angeles (UCLA). Many of the participants in these competitions later become members of the RRS as it is a very exciting thing to build a rocket of your own.
[6] The LR101 Project with Tomorrow’s Aeronautical Museum
RRS members, Wilbur Owens, Xavier Marshall and myself (Dave Nordling) have joined a project hence known as the “LR101 project”. This project is in coordination with Tomorrow’s Aeronautical Museum (TAM) at the Compton Airport in Compton, CA. This project team also includes students at Compton High School and at the local Compton College.
The short term goal is to build a suitable static test setup to hot-fire an LR101 vernier motor at the RRS Mojave Test Area (MTA). A link to the Heroic Relics website is below for more details on this small auxiliary rocket motor used in both the prior generation of Atlas and Delta vehicles. This small legacy rocket has been the core of a few liquid rocket projects in the past including at least one at the RRS.
The primary goal of this project is to renew and expand the RRS presence in liquid rocket testing. The team is working out the basic sizing and requirements at this stage. Later this summer, the RRS members on the TAM team can provide an update.

[X1] Update on the RRS Educational Events
Frank, Larry and Osvaldo gave an update on the latest educational event that the RRS started with Compton Elementary on March 8th. The program is well underway and they plan to finish with a scheduled launch event at the MTA on April 6th. The program, known as “Rockets in the Projects” is in partnership with the LAPD Community Safety Partnership (CSP). This partnership has been very successful in the year and half it has been in operation having had over 100 students and counting participating in the project. Not only does the society get the chance to give back to younger students, but also a chance to inspire younger people to be active in rocketry and science as they grow older.

[X2] Rocket Statue On Display at the 2019 RRS Symposium
The RRS events coordinator, Larry Hoffing, raised a question about the Rocket Statue designed by our society director of research, Richard Garcia. Although this statue was designed to be a permanent fixture inside the main gate at the RRS MTA, Larry had asked if a model could be assembled in time to have it on display at the Ken Nakaoka community Center when we hold the symposium on April 27, 2019.

Based on available resources and time, it seems unlikely to happen, but the RRS has managed to do great things in a short amount of time before. We shall see…
[X3] Cal Poly Pomona visit to the RRS
As a last minute addition to the agenda, James McPherson of Cal Poly Pomona made a short presentation to the society. James is the leader of the solid rocket team for the FAR1030 competition. The RRS has had a lot of experience in helping university groups with many aspect of solid motor design and build at the MTA. James had outlined a plan for their motor construction and the RRS was glad to review it. We did not have sufficient time at the March meeting to discuss Cal Poly Pomona’s project in detail, but we hope they can come back for the April meeting.
Jaren, Laila and James of Cal Poly Pomona stopped in to the RRS March 2019 meeting.
IN CONCLUSION
Our next meeting will be Friday, April 12, 2019, at 7:30pm at the Ken Nakaoka Community Center in Gardena. We’ll certainly be talking more about the symposium as it will be happening just two weeks later on April 27th. We also expect to have a summary from the next launch event at the MTA on April 6th.
If there are any questions or corrections, please contact the RRS secretary.

The RRS met for our February monthly meeting at the EAA 96 hangar at the Compton Airport on Friday night, February 8, at 730pm. The Experimental Aircraft Association (EAA), Local Chapter 96, was gracious enough to offer their main office boardroom. RRS members, Xavier Marshall and Wilbur Owens were kind enough to even provide food and drinks for our membership and guests. After reading of last month’s treasury report, we agreed to get an update next week as our president (doing the duties of the treasurer) was not able to attend this meeting. After the customary introductions of some of our visiting guests, we began the agenda.

(1) Discussion and task assignments for the 2019 RRS Symposium
The 2019 symposium will take place on Saturday, April 27, 2019. We have confirmed 8 of our 13 speaker slots and are working on building the panel discussion that will happen at the end of the symposium. We will likely soon fill all of our 13 speaker slots for the fourteen 30-minute sessions throughout the day. We have already confirmed several of our past speakers such as Northrop-Grumman and some new presenters such as the Air Force Space and Missile Command.
Frank said that the most important thing that all of our membership and friends can do is to spread the word and circulate our flyers as soon and as much as possible. Having an on-site food provider is in the works and John Mariano has offered to provide his brand, Celebrity Coffee, at the symposium. Based on the rate of (free) ticket sales through Eventbrite, we are on track to have a great symposium. We have 13 exhibitors confirmed and hope to have well over 21 exhibitors (last year’s total) by the time the symposium arrives. We are trying to pace events throughout the day to have a steady stream of participation from morning to afternoon.
Frank will soon be holding regular meetings to get as much of our membership involved with the myriad of tasks necessary to make the event fruitful and exciting. We ask all of our membership to do as much as they can. Ideas are always welcome, but people that can take action are appreciated even more. The RRS will not hold another symposium until 2021, so we would like to put as much of ourselves into this event as we can. Our symposium chairman is Frank Miuccio, please contact him or any of the Executive Council at any time.

(2) Improvements to the RRS social media presence
In the months leading up to the 2019 RRS symposium, the RRS should look at improving our social media presence. One of the things we will do is post different advertising flyer designs on our Instagram and Facebook accounts.
Alastair and Bill have had fruitful discussions on this subject and would like to have recurring monthly spot on the meeting agenda as the RRS social media presence will always remain important in our bid to reach new and old members.
(3) Formation of the 2020 RRS Constitutional Committee
The RRS is an organization that has persisted for a very long time, but periodically, the way we operate has changed over the decades. The last time a review of the RRS Constitution was done was in the 1990’s. Although some amendments have occurred to update our organization, it has been observed that many improvements, clarifications or simple corrections need to be made to reflect how we operate today.
Alastair Martin, Wilbur Owens, Larry Hoffing and Frank Miuccio at the February 2019 meeting at the EAA 96 hangar at the Compton Airport; a Rocketdyne LR-101 vernier motor sits on the table
The RRS voted and approved the formation of a three-person Constitutional Committee consisting of one Executive Council member and two people from our regular membership. After a solicitation of our membership at the February meeting, the following people will form this temporary 2020 Constitutional Committee:
Frank Miuccio, Vice President
Larry Hoffing
Bill Janczewski
This 2020 committee will first gather up all known copies and amendments to the RRS constitution. It is important to best establish where we stand before proceeding with the editing process. Frank has much of these records and with this collection of information, the committee will create a new draft of the Constitution. The intent is not to make many (if any) changes so much as to make clarifications of roles and responsibilities in areas that have been vague or entirely absent.
After a great deal of effort, the RRS has updated our membership roster as best as we have been able to do so. We continuously call upon our past and present membership to pay their dues and remain active during this important time. Please contact the RRS treasurer, Chris Lujan, or make your payment to the RRS president, Osvaldo Tarditti.
treasurer@rrs.org
president@rrs.org
With the 2019 Symposium around the corner, our priority is to execute the April 27 symposium. Therefore, the 2020 committee will not have to report back to the RRS until our September 13, 2019, meeting. Having the whole of the summer of 2019 should allow the committee to perform the laborious duty of researching and retyping the Constitution in such as manner that makes it clearer. The new draft or 2020 Constitution will then be reviewed numbered paragraph by numbered paragraph to assure a thorough review to approve portions that make sense and discuss others that may require adjustment.
Concerns were expressed about maintaining the requirements of our 501(c)3 educational non-profit organization when it was formed. These are important concerns which will be addressed. The committee will likely need to seek advice from our membership and they certainly will reach out as necessary throughout their working period this year.
This 2020 committee will then present their draft at the September meeting taking specific feedback and returning their final draft at the November 8 meeting. The new “2020” Constitution will then be put to a vote by our active membership. By our articles, this must be approved by a 2/3rd’s majority which may take some time to do. As any changes will largely serve for clarification, this draft of the Constitution, paragraph by paragraph should be able to be approved by the vote taken across our active membership with a deadline of the end of the year, December 31, 2019. Once the 2020 update to the RRS Constitution is approved, all prior drafts will be voided and the committee dissolved. Further, to avoid a permanent state of churn, it was agreed that after approval of the 2020 Constitution, no further amendments will be made for at least one year to allow the society to operate long enough to see where the problems are. A Constitution is a living document, but changes are purposefully not easy to make without a significant consensus of our active membership.
If there are any questions (which I am virtually certain that there will be), please direct them to the RRS Constitutional Committee chairman, Frank Miuccio
vicepresident@rrs.org
(4) Rocket Talk Radio
Alastair Martin has started a pod-cast called “Rocket Talk Radio” which is an hourly program that will talk about selected topics in the rocket business. These topics will be very relevant to the increasingly active world of space exploration. Alastair’s company, Production Tribe LLC, is producing the show to which RRS members, Dave Nordling and Richard Garcia, have agreed to be regular guests on the show. At the first show, we had Waldo Stakes as our first guest. As the show continues, Alastair will have other guests on the show to explore the many number of exciting topics happening today and in the near tomorrow.

Alastair Martin’s company, Production Tribe LLC, will be producing more shows soon and we hope to provide links on our website, RRS.ORG, from time to time. For those seeking ROCKET TALK RADIO, please go to Alastair’s website WATCHHOLLYWOOD.TV at the link below.
www.watchhollywood.tv
The next program is expected to be next week where ROCKET TALK RADIO will discuss the growing market of small launchers.
(5) Paintball Tanks and Regulators Used in Amateur Rocketry
Cameron Harrington is both a student at California Polytechnic State University in Pomona and a sponsored competitive paintball sportsman. After having some very interesting discussions about these commercially available, robust and mass-produced high pressure tanks and regulators, it is clear that they can be useful in building a simple pressure-fed liquid rocket. Ninja is one popular brand of these tanks and regulators used in paintball guns. The 4500 psi composite-overwrapped pressure vessels hold a finite volume (e.g. 77 cubic inches) of compressed nitrogen gas better suited for pressurizing fuel tanks. The Ninja Pro V2 regulator is adjustable by internal shims to allow a finite range of discharge pressures (350, 450, 550 psi etc) which work in small liquid rocket engines.

Cameron gave the society a brief overview of his experience with this hobby sport equipment and his experience in building a liquid rocket system. The society is considering buying a few of these devices for liquid rocket prototypes that will ultimately lead to a standardized design that the society can use and offer to other universities seeking a common-sense plan to flying a liquid rocket.

(6) Ramiro Rodriguez, Deputy State Fire Marshal, CAL FIRE
The RRS was happy to be visited by Ramiro Rodriguez, Deputy State Fire Marshall with the California State Fire Marshal’s office (CAL FIRE). Deputy Rodriguez has been with CAL FIRE for over 19 years and largely supports Fireworks and the Motion Picture industry. He is glad to visit with amateur rocketry groups to see what our concerns and needs are. CAL FIRE has been busy streamlining and examining their processes to better serve the public and groups such as ours who benefit from CAL FIRE..
RRS members Drew Cortopassi and Chris Lujan sit on opposite sides of our special guest, Deputy State Fire Marshal Ramiro Rodriguez of CAL FIRE
Amateur rocketry, much like with hobby rocketry, is governed by the state laws and regulations concerning fireworks. The four primary duties of CAL FIRE are prevention, engineering, education and enforcement. They train fire departments and fire service professionals. They also are responsible for resource management in the state of California such as forestry and watershed projects. They are the licensing authority for all 12 classes of pyrotechnic operators including the 3 classes of rocketry pyro-op’s. Ramiro answered questions by our membership and attendees.
Pyro-op’s must be 21 years old, have a clean criminal record and must submit an application to the state with five letters of recommendation from active pyro-op’s at or above the class level that they are applying. CAL FIRE is willing to accept expired pyro-op licenses as long as that license hasn’t lapsed more than a year. This is a common problem in many groups that pyro-ops allow their licenses to lapse out of financial necessity or simple neglect. The RRS is very active in our goals to acquire and advance more pyro-ops not only for our society, but for the amateur rocketry community at large.
Ramiro read some statistics from CAL FIRE’s database, that there are only 10 active first-class rocketry pyro-ops in the entire state of California. Only 10 active second-class rocketry pyro-ops and 34 active third-class pyro-ops remain throughout the large expanse of the Golden State. Concern has been raised by the amateur rocketry community about the difficulty in acquiring five active and relevant signatories when pyro-op’s want to advance their level. CAL FIRE is considering ways of making this process easier to do as they would like to see an increase in the number of rocketry pyro-ops in the state of California. The obvious solution is to require a lesser number of signatories for applicants, but CAL FIRE has not made a decision on exactly what they intend to do.
Concern was also expressed regarding the necessity of the two-year waiting period between achieving rocketry classes. Some applicants have a large amount of experience either professionally or in activities with their society. Ramiro had said that CAL FIRE does have some discretionary authority to recognize significant experience in proving an applicant suitable to advance to the next level, but he underscored the importance of log sheets and the responsibility of all pyro-ops and trainees to take accurate clear records of the work that they do. Put simply, the more familiar CAL FIRE is with your activities, the easier it becomes for them to evaluate you.
This is a rich subject which many more had other questions, but given the late hour, we concluded by appreciating Ramiro’s time and was happy to make his acquaintance. The RRS and CAL FIRE have had a long, positive relationship and hope to continue to do so. The RRS has extended an invitation to Ramiro or another deputy from CAL FIRE to come visit our private testing site when we will hold another event on April 6th with the student of Crenshaw Elementary with the LAPD CSP.

We also gave CAL FIRE an electronic file of our 2019 RRS Symposium flyer and have invited CAL FIRE to be a presenter and/or exhibitor at the Symposium.
(X1) Experimental Aircraft Association, Local Chapter 96
The RRS was happy to have our February 2019 meeting hosted by the Experimental Aircraft Association (EAA) Chapter 96 at the Compton Airport. Xavier Marshall is both an RRS member and the vice president of the EAA 96. The EAA 96 is encouraging hobbyists such as those in the RRS to become members as we have many areas of common interest. Aircraft and rockets require hands-on machining skills which the EAA 96 is willing to share with new members. To become a member of the EAA 96, you must join both the national and local chapter. Right now (but discount offer soon to expire) they are offering 3-years of membership for only $99 which covers both the local and national membership.

Xavier gave the RRS and visiting students from Cal Poly Pomona a tour of their machine shop which has a large lathe, a horizontal and vertical mill. The hangar is accessible to members 24/7 and the EAA has many members happy to help those needing to learn practical machining skills. This is a great opportunity for many of the RRS who do not have regular access to machining. The RRS is largely about making our own custom parts and the EAA 96 is an excellent resource to help.

(X2) Visit to the Rocket Lab at Tomorrow’s Aeronautical Museum
Given the late hour, we were unable to take our society membership and visitors on a tour of the Rocket Lab at Tomorrow’s Aeronautical Museum. Waldo Stakes has been very active in this project to bring a small group of Compton locals to build a small liquid rocket of their own. On display at the meeting was a Rocketdyne NA-LR-101 liquid vernier rocket motor that they hope to static fire at the RRS MTA. This 1000-lbf kerosene/liquid oxygen rocket has been commonly used in past amateur rocketry projects due to its robust design, however, as these surplus motors are becoming more scarce, it is important to appreciate having such an asset for learning. The RRS is happy to help the Compton group with their goals in flying this motor in a future design.
It was suggested that the RRS hold their March 8th meeting at Tomorrow’s Aeronautical Museum at the Rocket Lab. Although this is a fine suggestion, the RRS had planned to return to our regular location at the Ken Nakaoka Community Center in Gardena. That being said, the RRS would like to schedule an event at the Rocket Lab very soon. The RRS will let our membership know when this visit to the Rocket Lab can be scheduled.
(X3) Upcoming testing events at the RRS MTA
As was mentioned a little earlier, the RRS has set a new class with the students of Crenshaw Elementary School through the LAPD CSP. The first class will start on Friday, March 1, and run each Friday until the launch event we will hold at the RRS Mojave Test Area (MTA) on April 6th.
The RRS classes continue to be very popular and we are glad to share our hobby and passion for rocketry and learning.
RRS member, Michael Lunny, has been working with his local high school, Redondo Union, were they intend to enter rocketry competition to launch a rocket payload with 3 eggs and subsequently land it by parachute. We hope they can come visit the RRS at the next meeting on March 8th. Redondo has expressed interest in launching at the MTA in late March.
(X4) Groups wanting to test at the RRS MTA
For all groups interested in working with the RRS or with testing or launching from our Mojave Test Area, please download and fill out our Standard Record Form from the RRS.ORG website under “Membership” tab, then under “Forms”. All requests must be filled out with a complete set of contact information and a full description of the testing. The most important thing is to declare your test date and hold to this date as resources have to be scheduled. All requests must be submitted to the RRS president for the society to review.
Our next meeting will be on Friday, March 8th, at our usual meeting location at the Ken Nakaoka Community Center in Gardena. If there are any questions, please let the RRS secretary know:
The Reaction Research Society (RRS) held our first monthly meeting of the new year, Friday, January 11, 2019. We had a good turnout and a couple visitors from Compton High School. We thank Daisy Guevara and Jonathan Martinez for coming out to the RRS.
January 2019 meeting welcomes our guests and new members.
The RRS has student memberships available to those interested in becoming involved in our amateur rocketry society. To join as a student member, under 18, you must have your parent or guardian approval. Joining the RRS is the same as those seeking associate membership. The RRS website has a “Forms” tab where you can download our PDF membership application. Student membership at the RRS is $20/year. Regular membership is $40/year.
On the subject of membership dues, the RRS gives a reminder to all of our membership that you should keep your dues payments current. Like many in the society, I renew my membership at the start of the new year. The “Donate” button on the RRS website leads to PayPal where you can pay your membership dues. Please add “Member Dues” and your name to the notes. Others may make payment to the RRS president.
president@rrs.org
We also took time to welcome our new RRS members, Dmitri Timohovich and Waldo Stakes.

With the customary reading of the treasury report, we began the agenda.
(1) Pyrotechnic Operators in Rocketry
The first topic was about the RRS members that are working on attaining their pyrotechnic operator (pyro-op) license for rocketry. The California Fire Marshall’s office governs the licensing of different classes of pyro-op for theater, movies and amateur rocketry. The RRS has been on a campaign to expand our roster of pyro-op’s to both improve the knowledge of the subject as our membership and number of events annually grows.
Dmitri has a lot of professional experience in pyrotechnics and a lot of practical advice for applicants. Making copies of all your application documentation including your letters of recommendation is very important. He also shared some of his insight in how to best work with the California Fire Marshall’s office.
(2) RRS in Social Media
Our second topic was to talk about the RRS improving our social media presence. The Reaction Research Society has an Instagram account, a Facebook page and our YouTube channel (note that our name is truncated here), but we can always use more content. We need to find ways of expanding our presence in these areas to reach a wider audience.
www.instagram.com/reactionresearchsociety
www.facebook.com/reactionresearchsociety
www.youtube.com/ReactionResearchSoc
As the RRS embarks on more projects, we will have good stories to share. As both of our Media Officers, Bill Janczewski and Alastair Martin were away for the meeting, we’ll return to this topic at the February meeting.
(3) Spaceport L.A.
Larry Hoffing, our events coordinator, spoke about the RRS becoming more involved with Spaceport L. A. He has been in contact with Curtis Iwata and has had some discussions regarding the RRS joining a future Spaceport LA event.
spaceportla.com
Spaceport L.A. is also on Facebook.
Similar to the RRS, Spaceport L. A. is a non-profit group of aerospace professionals volunteering their time to hold events of interest to the public. Spaceport L.A. has attended the RRS symposium in the past. We hope to have Spaceport L.A. be one of our exhibitors at the 2019 RRS symposium on April 27th.
(4) MTA Facility Improvements
We had a good discussion of potential facility improvements at the RRS Mojave Test Area (MTA). The addition of the road sign at the first gate to the RRS MTA gives us a better way to welcome our guests. Our metal arch road sign at the MTA site entrance is also holding up nicely for two decades and still looking great.
Flo Jo Elementary and LAPD CSP pose before the RRS MTA sign
Improvements such as upgrading our restroom facilities and the central blockhouse are under detailed discussion. Osvaldo, our society president, has been leading this effort getting estimates and making a proposal for the society to review. It will be substantial investment in our facilities, but certainly well worth it to not only the society but the many guests we have from the city. Creature comforts are always appreciated.
Other MTA improvements such as replacing a damaged panel on the thrust stand structure. This 3/8-inch thick steel plate panel was permanently deformed by nearly an inch many years ago from a static test explosion. The goal would be to cut out the old panel and weld in a replacement while maintaining the positional accuracy to the overall design as best as possible. We have a waterjet machining provider willing to make a replacement set of plates once we can verify that the hole size and pattern is accurate.
We also discussed a project to run an electrical wiring trench between the observation bunker and the RRS alpha rail launcher will make conducting our school events easier to do. Anything to make set up more convenient in the hot summer months in the Mojave Desert is worthy of serious consideration. The material and equipment rental costs do not look to be prohibitive and the RRS may be able to get the conduit and panel materials donated.
We also talked about how to improve the mounting pad commonly used by our university rocketry groups over the years. The concrete slab has several male anchor bolts that protrude from the concrete causing a serious tripping hazard. They are also not in a regular pattern which other groups could use. This has been a frequent source of annoyance at the RRS and a better more regulated approach to mounting experiments is clearly necessary.
Concrete pad at the RRS MTA frequently used for mounting thrust stands, needs improvement
One solution is to cut away and grind down all male anchor bolts and install custom fitting trench plate with a pre-drilled and tapped bolt pattern on a regular grid pattern. This will be easier in the long run for several groups to bring their thrust stand hardware without having to match machine hole patterns by being present at our site. The regular grid pattern of holes would be described in an RRS interface specification that different user groups can use when designing their thrust stand attach points (remembering to oversize the mounting holes to allow for variation).
(5) 2019 RRS Symposium
Frank, the RRS symposium coordinator and society vice president, talked about the preparations that have begun for the 2019 RRS symposium. Invitations to potential speakers have began to be sent out. We didn’t have a lot of time to get into the specific assignments, but we will be talking a lot more about this subject at the February meeting. Frank has made our first flyer for the 2019 RRS symposium.
Our first flyer for the 2019 RRS symposium on April 27
(6) RRS Constitutional Committee
The topic of forming an RRS Constitutional Committee had to be tabled for the next meeting. This is an important subject that will be addressed in further detail with our membership.
(7) Rocket Talk Radio podcast
Likewise, the RRS participation in the Rocket Talk Radio podcast project had to be tabled for the next meeting. Rocket Talk Radio is a project by Alastair Martin’s company, Production Tribe LLC.
Alastair K. Martin, RRS member and owner of Production Tribe LLC at his studio in Hollywood, California
(8) SuperDosa project quarterly update
Quarterly update for the SuperDosa project was limited. Osvaldo had reported that Jack Oswald’s next ballastic test motor is nearly complete and that his RRS project team will be conducting test series to better characterize his solid propellant mixture.

(9) Next RRS meeting at the EAA 96 hangar
About once a year, the RRS (some years) has its monthly meeting in a new location. In 2019, the RRS has found a new meeting location for the February 8th meeting. RRS members, Xavier Marshall and Wilbur Owens are members of the Experimental Aircraft Association. Chapter 96 of the EAA is located at the Compton Airport. Xavier had offered the RRS the use of the EAA 96 hangar’s offices, so the RRS will hold our February 8, 2019 meeting at the same time, 7:30pm. This is only a temporary change for February only just to allow our membership to visit the EAA organization and tour their facilities.
Xavier will provide more details on how our members can get access at the Compton Airport. I will share these details on this website at about 2 weeks prior to the event.
(X1) Celebrity Coffee
Long-time RRS member, John Mariano, paid us a visit to the January meeting. John has been busy with his new business venture, Celebrity Coffee. His business will be a local coffeeshop featuring music and a warm environment to his customers. We hope to visit his shop soon.

(X2) Next LAPD CSP event
The RRS is getting ready to start another school event through the Los Angeles Police Department’s (LAPD) Community Safety Partnership (CSP). With the looming Los Angeles teacher’s strike, the start date could get moved. We plan to hold the final event of this series at the RRS MTA as usual. This launch date would likely be middle to late March. More details to be coming soon.
IN CLOSING
We adjourned well past the Ken Nakaoka Community Center closing time of 9:00PM. Our next meeting will be on Friday, February 8, 2019 at 7:30pm.
Again, please note that this February 2019 meeting will be held at the Compton Airport at the EAA 96 hangar. Please arrive between 7:00pm and 7:30pm as the EAA must let our attendees in through the Compton Airport gates.
Also, please note that this is not a permanent change of location as we will hold our March 8, 2019 meeting back at the Ken Nakaoka Community Center in Gardena on our regular 2nd Friday of each month.
If there are any questions about the topics covered in the January 2019 meeting or anything you’d like to see on the February agenda, please contact the RRS secretary
