About 10 years ago, I just stop playing with my RC Car & Heli (due to no time). I just recently trying to make time to get back into RC's. The engines are now locked in position. [:@] I open the side crank case and see some rust on the crankshaft/connecting rod point. I spray it with WD40 last night trying to free the motor.
Is there any other fluids I can use that is better?
Replacing 3 engines is not an option I want to do.[
Thanks in advance.[8D]
