I'm trying to airstart a couple of Aerotech F-20's. The problem is e-matches are too large to fit in the nozzles. So I made some igniters from 30 guage wire soldered to a short piece of nicrome wire then dipped in pyrogen. They tested fine but my last flight yielded one only burning half the pyrogen and the other not any. I'm using a perfect flight mini timer 3 with a nicad rechargable 9 volt.
I'm also thinking about front-end e-matches for these single use motors. Has anyone tried drilling a hole in the foward end of a single use, inserting a pyrogen dipped e-match, then epoxying the forward end to seal it? Since these will be air-started the ejection charge will not be needed.
Thanks guys
