This is also the source for information on the Rocketeers Of Central Indiana (ROCI), Section #625 of The National Association of Rocketry (NAR). Feel free to check here for information about ROCIs launch events. The launch events are conducted throughout the warmer months at the Academy of Model Aeronautics' Headquarters and Aeromodeling Center in Muncie, Indiana. This facility is the finest flying field in the state and ROCI is proud to be the exclusive host of the rocketry events held there. ROCI is not currently conducting meetings as we have lost our meeting place.

Cert 1 12 years 5 days ago #440

I was thinking of having my dad certify level 1 with my rocket is this allowed? That way I..... I mean he can fly H + Is. I was looking at Aerotech 38mm motor casings. I know that he can get those, but it says you have to be certified to get the reload. So, how do you get a reload so you can certify? Once he is certified can he fly my rockets under his name? Also what kind of things do I need to implement in my rocket so that it will be a successful flight?

Anything helps. Thanks, John Wedding

John,

In order for a certification to be "legal" one of the requirements is that the person attempting the certification has built the rocket. They will need to be able to answer questions about it like where the center of gravity is, where the center of pressure is and how they determined those.

The process for getting a certification motor is actually fairly easy. You are allowed to buy 1 motor for certification purposes. This is normally done by an on-site vendor. If you pass the certification flight, you can buy as many as you'd like. If for some reason you don't pass, you can try again buy only buy 1 motor for that attempt. You can keep trying as many times as you'd like but you can only buy 1 motor at a time.

As for advice or tips, I would pick out a good kit for a level 1 certification and before you start building it, read the instructions a few times and then ask questions. Ask why things are done this way or that way. After all that, fly the rocket on a large G motor a few times to see how it does and make sure that it will be stable and a good flight.

Lastly, this is not a race. It doesn't have to be hurried. You should take your time and learn as much as possible and enjoy yourself as much as possible. I know people that have been flying rockets for decades and they're not certified to fly high power but they enjoy every launch.

Good luck,

Alright. Thanks for your help Aaron. Well since I cant certify yet are there any kits I could build or articles I could read, so I may learn new things in this sport?

Once Again, Thanks John Wedding

John,

I would suggest a few kits and each for different reasons:

1) LOC Lil'Nuke - This is a smaller kit that flys on 29mm motors (E through H) It can and should be put together with nothing but yellow wood glue. It should be modified to include a baffle ejection system, kevlar or nylon shock cord and a better shock-cord attachment. This is the basic mid-power kit but if you build it for high power motors it will be able to handle them just fine. There was one launched this past weekend on an H128 and it was a great flight.

2) Estes Interceptor E - This is a difficult kit that should take quite a bit of time. It includes many small parts and detailed paint job. This is to help with painting a rocket and applying decals. You'll need to use a mixture of glue types for the different materials.

3) LOC Viper 3 - This is a basic cluster rocket of 3x24mm motors. It will help with clustering and can be built with yellow wood glue and/or 5 minute epoxy. It will also show a different type of motor mount and fin attachment method. Modifications include a baffle and shock cord change similar to the Lil'nuke.

4) PML Mini Black Brant with CPR. This is a level 1 capable rocket. It will help with electronics (dual deployment), through the wall fins, multiple fin sets and piston deployments. This rocket can be flown on G and H 29mm motors. Later you can add a booster stage and fly it on an I to H 2-stage configuration.

Lastly, pick a kit that looks challenging to you. A scale kit like the Semroc Saturn 1b or Cosmodrome Aerobee Hi would be something that should be interesting and challenging at the same time. If you can master hard kits like those, you'll be ready to move on.

Ive built the Loc Viper 3 before, but it didnt work out so well, because I read the shock cord mounting instructions wrong. I was just reading mark's 10 challenges for me for fun, but I dont have a clue how deul deployment works. Does anyone have one that they would be willing to bring to the next meeting? I'd like to learn how that works, since I hope to be at the next meeting. Ill have to double check with my mom though.

Thanks, John Wedding

John,

If you still have the LOC Viper 3 you can repair it, add a baffle, add a better recovery attachment point and fly it again. Repairing rockets is almost as important as building them because all rockets will get damaged.

I would suggest that you remove the LOC epoxy blob that holds the nylon line that the elastic ties on to. Next, find a copy of SportRocketry from May/June 2008 (I have a copy I can lend you if you can't find one) and build one of the baffles that are described on pages 34-38. Part of that baffle should be an eye bolt or u-bolt that you can tie some tubular nylon onto. This will protect the parachute and nylon from the hot ejection gases, give you a better attachment point for the nylon and remove the need for wadding so the rocket is easier to prep for launch. Since it is a 3 motor cluster, it will give you a chance to learn how to wire igniters together for a cluster or how to make a multi-motor clip-whip.

Keep asking questions. It's the best way to learn.
