I've flown some Aerotech motors that old. I don't recall any problem igniting them. The problems you might encounter are:I have a couple of old 24mm single use Aerotech motors and I was wondering if there was any chance of ignighting them succesfully? Any tips or pointers would be appreciated.
I would leave the little bit of dust. Its only a little bit but it will help the motor not chuff and kick on instantly.I flew some reloads that were 13 years old. no problems!
On your 24mm motors take a piece of stiff wire about 1/8" diam ish.
stick it in the motor like it was an igniter, run it in and out a few time to "scratch" up the surface of the propellant a little bit, (to expose fresh propellant) tap the "dust" you made out of the motor,
and it should lite up like it was new.
Be smart use some common sense dont gouge the surface just scratch it up a bit.
