    Weekend Hybrid Flight

    Flew my first Hybrid in some time at the SC Rocketry Launch this weekend. The rocket was a 54mm G10 with Acme Fin Can. The max altitude on the I-260 was 3,085 feet. Many thanks to Johnny Hoffman for his GSE, Robert Carson for continuing to support and sell the Hypertek System, and Chuck...

    HyperTek anyone?

    So is anyone out there still flying HyperTek motors? While going through my rocket room the other day I came across a case of motors and it got me wondering if anyone was still flying them. I probably have two cases of the 54mm motors and probably around 10 of the 98mm reloads. Tim Sapp

    High School Hybrid Rocketry

    I've been experimenting with rocket engines since the sixth grade. As time passes, the designs for which I aim become more and more complex. I've reached the point where I actually have no idea what to do. I'm trying to make a mid-power, single-stage hybrid rocket with enough thrust to get some...

    Found Tribrid Engine

    I've been wanting to get more into hybrid rocket engines. If anyone has a tribird engine for sale please reach out to me. I especially would like a RATTworks K350, but I would consider any production tribrid or clone. If you aren't familiar with these engines, you can learn more here...
