Some tips:

Burn off all fuel in engine after done flying.

Add afterrun oil into the crankcase via the vent to lube the bearings and prevent them from rusting out early on you. Coolpower has no castor oil in it and the synthetic oil won't put a protective coat on the bearings like castor does.

Add 3 oz of castor to Coolpower or any other 100% synthetic oil fuel. This small amount of castor won't cause any castor oil buildup problems but give you a little extra protection in the long run.

Run your engine about 400 rpm rich of max lean rpm-verify with a tach.

Every season or every 6 months if you fly all year round, check the valve lash and adjust as necessary.

Every season or every 6 months if you fly all year round, check the tightness of all of your bolts on the engine.
