Notes for G-Force 2206 O-Ring keeper mod

So you got yourself a shiny new G-Force 2206 and stick it onto a new EPP plane and on the first flight! Zip!!! the prop goes for a flight on it's own away from the airplane..

If you have played with Foamies long enough you have probably learned that wobbly adapters on these motors can be finicky to say the least

one problem i've run into, and this motor has it too, is they (the manufacture) puts too short of screws on the adapter to catch the O-ring or band that holds the prop on.

Digging through your stash of screws (if you have one, you don't? well you should!) you might find some suitable M3 screws, in this case they need to be about 2mm longer than the stock baby ~5mm screws they use.

You will find One more problem, the clearance with this motor is very tight and most M3 flat head screws have too Big of a head. This will make getting the bands on or off nearly impossible..

so here is the fix, find some ~7mm flat head M3 screws and chuck them in your drill, even better is a drill press. Use your Dremel with a grinding stone on it to grind the head diameter smaller while you spin the screw with the drill, this way the drill acts like a lathe and you get a nice round and smaller head..

These screws serve two purposes, one they hold the o-ring or band that keeps the prop on, and two they hold the end bell to the shaft, so a dab of blue or red threadlocker is a good idea on these screws.
