3/16" ID rear hooks

Make your assembly with a short length of 3/16 Al tube.
Wind your motor outside the model on your stooge, then use your inserter stick to hook the
wound motor assembly onto your 3/16: rear peg which you have already in the model.
A simple 1/4 turn will now lock it in place, withdraw your inserter stick and attach a
prop and you are ready to fly.
