RE: Sundowner 50 Arf
So far I have only used the recommended break in prop 14-6 apc. I am taking it easy on this engine letting it break in nice and easy because I plan on running this engine hard later. I have switched to a 13-8 apc but have not had a chance to fly it yet. I am going to see what it does with this before I jump to a 13-10.
