Ask who has experience with the Whirlwind blades, David Joyce has recently
fitted them but not done much flying yet, (approval issues with the LAA)
They look=C2- and sound very nice, much less harsh than the Warp Drive bl
ades.btw 3 blades will be smoother than 2, (which is why 2 blade windmills
fail much sooner than 3 blade ones)

Hello Marcel, all,
yes - I'm fighting symptoms and of course I know, that it would be better t
o rather fix the source of the problems thoroughly instead, which obviously
is, what Frans did (Frans - thanks a lot for your far-reaching explanation
s, your offer to have a look and btw good to know you're well off :-).
I've learned, that most live with the cooling shortcomings of the Europa so
mehow or investigated and found their own ways to cure it (like David Joyce
, who left it all like it is and changed to another propeller). At least I'
ve read about and also saw many interesting solutions. Bud Yerly in Florida
did something different than Frans who did it different than Neville Eyre.
....
What I forgot to tell you, but what is most important for the whole discuss
ion: I didn't build my Europa but bought it second hand. Those who found th
e best solutions are also builders or even worked at Europa Aircraft or hav
e a shop, like Bud. What Frans and Ilona achieved or Bud Yerly does for his
customers is way beyond my skills.=C2-
So I came to the conclusion, that I have to buy a Woodcomp, SR 3000 W, whic
h seems to be an adequate fix for the cooling problem and adds a tad to the
performance as well (since I want to keep the rest of the setup as it is,
like David did, I'd also chose the 3-bladed and not the 2-bladed for that r
eason) or I make a flap in front of the cooler, like a friend in Belgium di
d it at his XS Mono 912S. Another option might be the new Whirlwind blades
with a wider chord in the Airmaster hup http://www.airmasterpropellers.com/
products/productdescription/type/view/id/67/ww-r64w, but I don't know yet i
f this is sufficient, since they are comparatively new. Obviously this woul
d be much cheaper than a new Woodcomp with Controller.
At least my "only" cooling problem is SOLELY ON THE GROUND and in a couple
of years, even though running the engine with a thermostat I never actually
had to shut down the engine due to overheating. So I have to focus on that
problem during ground operation.
Anyway thanks again to all for your input - much appreciated!!
