What fuel do you use for your rockets?
How did you get to launch them at KSC? As it looks like in the background with the rocket garden.

Does anyone know where I could get a good model space shuttle for around $20. By the way I'm in the US.Thanks
You have guts... Launching a Centuri LJII.. Very cool. Paul
I also have the guts to launch my Centuri Saturn - V!!

I built a Jupiter 120 based on a BT-70, which would be a 1:152.72 scale model.The SRB scale diameter is 0.945 inches. I used a BT-50 since I had that handy, so the model SRBs are a little oversized. The Service Module (SM) scale diameter is 1.220 inches, so my BT-55 SM is again a little oversized. This version has fixed SRBs and will flies on a single 24mm motor. The complete build thread is over on The Rocketry Forum at http://www.rocketryforum.com/showthread.php?t=44788 with complete drawings and patterns.I finished the model back in May, but was not able to fly it until today. Here is the liftoff pic and a shot of it under the chute. The LH SRB came off when the chute deployed, but suffered minimal damage. A little epoxy and this baby will be ready to fly again!!Many thanks to Ross and the Direct Team for checking my drawings and providing assistance.
Great build job, David! I'm going to have to go back through your buildthread at The Rocketry Forum and save those files you provided. I lovethe way your finished product looks; no way I could come close to the quality you put into it. Well done!

Well done!Thanks Dave, this was my first "serious" scratch scale so I appreciate your kind words...I wanted to make powered SRBs that would separate, but figured I had better crawl before walking or running BTW, I have seen your postings and you do great work!
Your best bet for the design & operation of the powered SRB's is to checkGeorge Gassaway's website (or maybe contact him directly); he's successfully done this with his large scale Space Shuttle models and hasthe plans available. There's even a video clip on his website showing thistaking place. You may have to upscale your model (consider the one youhave a boilerplate) to make the powered SRB's work. Good luck and letus know how it goes!
