Preferd props

[Ironman Al 35]

Maybe some one can explain the difference between the Warp drive and Wirlwind carbon fiber adjustable props? The mission for the plane is short take off and landings in mountain conditions, high spead flights are not that important or extreamly long range flights. Ive got a Rotax 912 ul now, the people installing the engine upgrade bigbore or zipper kits in Utah are putting wirlwind carbon fiber 3 blade props on, they look very different from the warp drive g.a.p. that I have.  Is there s difference in performance? And at what?

Just and Kitfox are both fans of the Whirlwind props these days.  They claim the prefrmance is superior to the warp drive in all aspects.  I can't give any first or second hand info other than that. 

I had a warp on my yellow plane and it worked really well.  Now I have a Prince fixed pitch on the Mangy and am happy with that.
