Just bought a bunch of Aerotech D10 / D21 / E15 SU motors from ValueRockets.
Never launched anything other than Estes and Quest A-D engines before.
Any tips for getting the best from these?
I've got the usual suspects rockets to use them in... Everything from BT20 min diameter to BT60 birds like my Vagabond.
Anything special needed to get the ignitors to pop?
