Default O360 RV-4

Dayton,
I have a old Air Force buddy that made the same conversion to his O320 wood prop RV-4. He used a WW 151 prop so the CG would workout. It had incredible performance.
Go for it!
Danny

Geee....adding a constant speed prop means he's going to have to upgrade his throttle quadrant! I told him I might have a recommendation.....

I have the WW151 prop, and the CG is dead on with amazing performance. Have WhirlWind make the “old” style blades for the prop... 1 mph slower, but the acceleration and deceleration are incredible.

An O-360 or IO-360? Also I can't help but wonder if the pound per horsepower equation works out or whther you might not be albe to extract more HP from an IO320 without the weight penalty of the -360?

Just musing.

Chris
