David,
Good point! When I first moved to high power I couldn't figure out
how to retain the motor any other way than an Aerotech retainer.
They're on all of my high power rockets and the only thing I use.
I've heard of folks using tape between the motor and the motor tube
(old school) but every time I try that on a model rocket I eject the
motor so I've not tried it on a high power rocket. The retainer is
just a required part of the rocket that isn't usually provide - same
as chutes, chute protectors, and shock cords.
Thanks,
Mike
