Flew my P47 Tarheel Hal with the FG-60R3 this weekend. Flew it 8 times for 8 minutes per flight. Its the hit of the field, everyone comments how awesome it sounds, especially at idle. I did a few low passes towards myself and you can actually hear the valves and rocker arms ticking as it soars by at about 100mph. Love it.
I tuned it so I have good transition between idle and full throttle, but full throttle runs a little bit rich. I can hear it hit a clean RPM then I can hear it burble a bit and lose RPM, so I chose to fly it at that setting.
About 95% of the time in the air I was flying at half throttle. Didn't notice much difference between half and full throttle. Half throttle is plenty of power to do scale maneuvers with.
Idle is solid, never had any issues with it idling low, even on final approach.
Temperatures on cylinder 1 never climbed above 305F, and the other two cylinders stayed below 285F throughout the entire flight.
I notice some spray coming out of one of the exhaust fittings to the Keleo ring so I'll probably take that fitting apart and use a little more red RTV this time.
No screws are loose.
If the engine didn't start after 5-7 flips, I'd open the throttle and use a fuel bulb to apply pressure into the vent line. This pushed fuel up into the carb. I'd close the carb and the engine would start after 1-2 flips.
Pretty happy! Now I'm praying I don't blow a cylinder off because that means deadstick and deadstick at my field is a challenge.
Heres some videos. Sorry the videos aren't the best, the camera man had a hard time finding the plane with my iPhone 6s!
