Which is better a 3 or 2 blade? I am having problems with a Thunder Tiger GP42 getting too hot while running. It has a 3 blade 9X6 and the engine is cowled, I am running 15% fuel. I have put pleanty of airflow holes in it. Could it be possible the 3 blade prop makes it work too hard? I am thinking of switching to a 2 blade. The plane is a Tower Voyager.
Thanks
