Hello...I have a couple of kits that are in need of motor retention (Loc
Onyx & Estes Oracle using 24mm RMS). I wanted something simple and light
weight. My idea is to screw a couple of small screw eyes into the rear
centering ring on either side of the engine (in the oracle, it would be into
the plastic at the rockets rear with the screw on part removed). I would
then stretch a piece of Kevlar between the screw eyes (affixed with snap
swivels at each end) with a the Kevlar forming a loop around the base of the
nozzle. The engine itself would be installed using normal friction fitting
and the Kevlar harness would be serving as a safety belt in case the
friction fit wasn't tight enough. Anybody see any problems with this
technique...in my mind's eye it looks like it should work. It's not as
strong as a clip, but given that it is just acting as a back up to friction
fitting it seems like it should work okay.
