Onboard video from my 1.67x upscale Comanche 3 model rocket. Date of this flight was 6/21/14 at MMAR field in Muskegon, MI. Flies on F39-4 to D12-5 to E9-6. Each booster has a parachute and the upper two motors are airstarted by a custom controller I built for this model. This was an OK flight but the controller reset after lighting the sustainer motor so the main chute never deployed. It came down with just the drogue but it landed in tall grass with no damage. 4FlyRockets has a very nice video of an earlier flight of this model here: http://youtu.be/kVeugn5UN4E While this was an entirely different controller, it had a similar issue where the main chute never deployed.
