Yes - I have the Airmaster prop - and the High-top seems to be faster than the
stock configuration (I have talked with other Europa builders with the High-top
and they agree). We built the kit for the High-top ourselves - more frontal
area but faster? Streamlining is still a black art. But it sure is more
comfortable
and feels much more roomy - in the stock Europa I feel like I am driving
a 1957 Porsche Speedster with the top up. I also fly a Mooney M20 (1968) and
even though the width of the cockpits is exactly the same (44 inches with the
cutouts at shoulder height) the Mooney feels claustrophobic. Even the Boss (my
wife) would rather travel in the Europa. In the Mooney she does her co-piloting

I have the speed kit fitted to my XS but I dont have any transitions to the
fuselage
or wheel fairings. Are these available from Europa or are they something
each builder makes for himself?
Cheers

30% of the length. For a 3D fairing things get a bit more complicated. Shorter

I have wheel pants and fairings (the speed kit) on my Europa Tri-gear High-top
- speed kit built by Bud Yerly. I went from 119 kts to 137 knots (at 1000 ft
full
throttle) after putting them on. Talk to Bud - I don't know if he still makes
them
but I am very satisfied - and they are easy to work with - one bolt, two screws
and a pin and they are off. After 400 hrs. and 8.5 years only slightly dinged
up (dumb tax for not being more careful rolling the plane out and hit a
door guide in the hanger).

Frans,
Reading your improving nose wheel fairing , did you achieve good results ?
Did you make more than one ? I am currently in need of a nose wheel fairing ,
Also
need a full set of leg fairings , including transitioning to fuselage and
main wheel pants / wheel fairing ..
Im pressed for time so cant make my own at moment , dont see point of making
fresh
moulds when , improved ones are sitting on a bench somewhere ..

Kevin
