ptgarcia,

Your one post ("...once I run the plane out of fuel...") seems to indicate that you are leaving fuel in your plane. To prevent engine corrosion, you should completely drain your tank and burn off any remaining fuel in the tubing and engine at the end of each flying day.

To accomplish this, hook your fuel pump up like you are going to fill the tank but run the pump backwards to extract the fuel. Once you get all the fuel out of the tank, turn on your plane and transmitter and open the throttle all the way. SECURE THE PLANE, then start the engine and continue to try and re-start the engine until it won't fire any more. Remember to SECURE THE PLANE via restraint, helper or firm grip before starting at full throttle.
