Hi Ira,
I have 630 hours on my Airmaster AP332/WarpDrive and I am very happy with the
reliability
and performance of this prop. But the cooling problem on the ground
with the WarpDrive blades is a big inconvenience, with any engine. All Europas
I know, fitted with the WarpDrive prop, fixed or variable pitch, even with the
80 HP 912 have this ground cooling problem as soon as they have to wait more
than a few minutes at the holding point in hot weather. With the existing Europa
XS cowl, I believe the only solution would be to have wider blades at the
root and higher twist, as offered by Woodcomp.
