I stand corrected. That round-off will get you every time. Or in this case, not get you.
My sim shows 3195ft @ M 0.74 - still haven't had a chance to fly it yet
Well acording to Open Rocket it's not
Perhaps the wrong motor. Apogee sells the Aspire bundled with the F10 motor for a mile or the G74 for Mach. Note that it isn't trying to do both with the same motor. I think Tim even suggests different fin profiles for the different objectives. Point being that this is a mod power model.
I have a friend who says some day he would like to fly at Mach 1 and 1 mile. Can it be done mid power? If so what is the smallest motor/rocket combo?
24mm Carbon Fiber tube (13") with F44-8W will do it, Sims say 5800 feet and mach 1.2. Finding it... yeah, not likely.
look at post # 18 :eyeroll:
the G80 is not the largest motor under 80 N of average trust. The Aerotech G-80 is 136N total, an Aerotech G75J as 157 N total and a CTI G54-RL 160 N total.

He left out an s on the total impulse. Thrust is measured in N (Newtons) and total impulse is Ns (Newton-seconds). The average thrust of a model rocket motor can not exceed 80 N (Newtons). The total impulse of a G motor is 80 Ns < Total Impulse <= 160 Ns (Newton-seconds).I was simply pointing out that the 80 was the largest average N rating allowed for non-cert flights. I also pointed out that it did not mean it was the best motor. Depending on the build, total impulse does not always mean the best motor for the rocket. I learned that the hard way. But I learned it.
so show me the simm, because I can't reach over 5000 feet with Open Rocket.
:yawn:Dood. Are you going to resurrect every dead thread even remotely close to this topic?
