Hi Paul,

Could you please confirm that 17 gph figure you stated for Tracy's plane, once again? Seems quite high to me. Thanks

Bob

That is based on flat out running full rich. You would get nearly the same fuel burn
with a Lycoming O-360 180 HP or a 200 HP Continental IO-360.

Tracy does not cruise at that figure. It leans it out and cruises around 170 or
so and less than 10 gallons an hour. At cruise speeds the same as a Lyc O-360
powered RV4 Tracy gets the same fuel burn in his rotary powered RV4.
