Default Magnum 70 RFS

Anyone running a Magnum 70 4 stroke ? I have a new one still breaking in .

MA K series 13x6 8600 rpm's idle 2650
TF PP 12x8 9150 rpm's idle 3400

Idling smooth with the 13x6 , but does not seem to like the wood prop for idle. Top end seems a little eratic , but I'm hoping that clears up with a little more run time.

Four strokes like heavy props for flywheel effect.
