Hello Michael,

I am also an Speed freak and we offer an Speed Carbon prop in 16x20 for Engines 70-80 in 2 different Profiles. One for more Rpm and normal engines, and one with 30 % more Power for Better engines with less RPM and more Speed.

We also offer 2 different 19x22 Speed Props for the 150 Engines.

Take a look at my Page www.air-c-race.de and go in the Shop look under Propeller

Hope can help you...
