I've been designing a rocket in OpenRocket for A motor Altitude competition. Right now the C class A Altitude record is 449m. In simulation I can only get my rocket to around 380. Part of the problem is that I get deployment before Apogee. How are people getting that kind of height with only a 4 second delay? Is there any way to lengthen the delay? Or are we just doing away with ejection and letting them free fall back?
