Slow Stick Parts
Patrick,
Easyest way out is to by a new motor/gearbox for about $15.00, or get yourself a complete set of new parts by spending $32.00 for another SS kit and using it as a parts kit, the plane is one of those great flyers that comes along every now and then and is worth having the parts on hand if you have to repair it, and you will from time to time.
If you stop to think about all the fun you are having with it thirty two bucks for a complete parts kit is cheap insurance.
