It would be worth researching exhaust extraction. I have it on my Lycoming
(pusher Long EZ) and it works=0AWarm day, full throttle on the ground for 1

630 hours on my Airmaster AP332/WarpDrive and I am very happy with the rel
iability and performance of this prop. But the cooling problem on the groun
d with the WarpDrive blades is a big inconvenience, with any engine. All Eu
ropas 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 t
o wait more than a few minutes at the holding point in hot weather. With th
e 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. =0ARegar
