Default RE: Anyone got readings OS Fx 91?


ORIGINAL: mfuess

I have to disagree with you on this. I have an OS 91FX on a pylon plane and it turns an APC 12x8 prop at 13,500 RPM on the ground, and 14,700 in the air. My engine runs perfectly every time, every flight.
MFuess,


I agree with you, as long as a good, high-performance aftermarket exhaust, like the Nelson UltraThrust , or the JettStream is installed, along with a suitable.

With the original muffler with the baffle in place, this engine will be happier doing 10-11K.
