For you RV flyers, Van 'his own self' wrote an article about it years ago & said that due to the wing planform RV's climb just as well at 120 as 90 so just cover ground while you climb & cool better in the bargain. That was obviously with Lyc power. IIRC, it was due to the drag going up rapidly at the higher angle of attack when trying to climb at lower airspeed.

Thanks Charlie,

I am inclined to buy that.  Have not tried higher angle of climb since new prop and gearbox - but, I have found that 120 MPH was the best compromise between climb rate and cooling with the old combination.  On a hot day 140 mph IAS as Bill Eslick is using might even be better.

Ed Keeping fingers cross for tomorrow's weather.
