Hey Norm.
Are you intending on using the rocket first and then using prop power? If thats the case...that sounds awsome and i can help a bit. if not....well....you might want to rethink that idea.

Umm...well i just reread your question. Bad news. A brushless inrunner running 60mph is no big deal but that small and that light...well you mite just kiss that plan good by. If you could mount an EDF jet to it then you could supposidly reach 60mph. You would be able to have more weight because the motor is closer to the CG. I just dont know how you would do that with the current rocket set up. over wing maybe?[sm=confused.gif]
