This is a cool design! I don't know if airstarts are going to anything except give you practice for the bigguns', but it oughta be cool! Keep us up-to-date!

Yes, the air-starts are mainly for effect.

I got a chance to fly it this weekend at the Whitakers launch on a F21-4w! Very cool flight, perfectly straight up and quite fast for a 2.2" diameter rocket. By next month i should have the timer set up so i can start with 4 A10-PT's and Airstart the F21 about a second into the flight. I still need to post some pictures, maybe I'll try that after homework tonight...
