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. Craig
