I would talk to the folks at Airmaster; they did extensive testing for their
prop using the Europa as the test platform! They seem like pretty smart
folks and worked with Warp Drive during the development. The Mono wheel may
have some blade length compromises due to the ground clearance but I don't
know. I don't think Rotax would recommend switching gears around between 912
and 914. I sure like my Airmaster, its worked great for 6 years.

Subject: Europa-List: propeller optimization
I spoke with a gent at Warp Drive who explained that with the short blade's
used on the europa, the blade pitch angle needed for higher speeds can be
greater than optimal causing turbulance near the tips.
He told me they can modify the blade near the tips to alleviate this problem
and pick up 5 or 10 kts. He also said it would be better for the europa if
one used the 912 gear ratio (2.27:1) rather than the 914( 2.43:1).
Has anyone tried the constantspeed blade planeform from Warp Drive? or used
the 912 gear ratio on the 914? if so was performance improved?
