I am new to Nitro engines and have a plane that came with with Plastic Spinner. The engine is a Super Tigre 45 which is an ABC non-ringed engine. It is very tight. I just tried to start the engine with an electric starter and it melted the outside of the spinner! It could not turn the engine over. I can turn it over by hand but it is tight. Should I just buy a replacement aluminum spinner or is the engine defective? I read in another post that plastic spinners can explode, and I can see why, so I am kind of scared at this point!
