I have a P-51 motor in my Champ. The stock motor failed relatively quickly on me. It was a drop-in replacement, fits perfectly. The power lead is a bit longer on the P-51 motor.

I don't have any way to accurately measure the exact thrust, but I'd say that it's in the 1:1 area.

I am using the stock prop and 160 mah Turnigy and Poweredge batteries.
