Thanks guys, prop clearance is not an issue on this plane, so I guess I'll just stick to the 12x6APC. I just wasn't sure if the 60FP would benefit from a little more RPM's or not. Being a lower powered bushing engine she probably can't get the RPM's that her bearinged siblings can obtain. The Phoenix Decathlon does fly very well with this motor and I don't think overpowering it would be very beneficial.
The Decathlon does very smooth rolls, loops and inverted flight is a piece of cake. I find that the rudder is extremely effective on this plane and has to be applied very carefully. The tricky ground handling was to be expected with the short coupling. But she lands just about as well as a trainer.
