Re: RV's


 

From a long time (see my sig) RV owner, the C/S prop allowing full power in acceleration and climb obviously helps, but I'll bet it was at least 74" diameter, too. Many of the F/P prop makers sell 68" props for RVs (and likely Tailwinds). That extra 6" of diameter makes a really big difference in acceleration, even with a F/P prop. I've played with various diameter F/P on my RVs I've owned over the years, and the most impressive was a Warnke 72" diameter on a 160 HP RV4. Great takeoff performance, and 170 kt (not mph) cruise.

On tire pressure, if the guys at Van's are recommending 25 psi, they're doing it to hide the shimmy issue. I've always run 50+ in mine; if I forget to air them up and they get down to 30 psi or so the plane feels like a '68 Pontiac station wagon on the ground; I hate it.
