 Posted: Sun Oct 22, 2006 1:41 pm Post subject: Prop Blade Length |
 |
|
Does anyone have ideas about what length propeller is optimal on a
Series 4 Kitfox?. At one time Skystar (remember them?) recommended a 72
" blade, and Warp Drive suggest a 70". I am using a 70" 2-blade Warp
Drive prop on my 912 UL powered C4 .
Thanks,
Dick

I don't know any recommendations, but I received a 70" three blade as part
of my fwf kit.

Blade length depends on RPM, longer the better up t 72" for a Fox (ground
clearance) so long as the tip speed is not too high

I just pulled off a 68" GSC wooden prop off of my Speedster with a Rotax 912UL (80hp). I replaced it with a 70" or 72" (I forgot to measure it) IvoProp ultralight. Huge improvement in both takeoff roll, climb, and max straight-and-level speed. It was 2.4 lbs lighter as well. After I get the pitch dialed in, I'll run the numbers by you guys.

John is right...it's 70". I forgot to mention that it's a 3-blade. I'll provide results on a separate post when I get time to develop some solid flight data.
Thanks again to the McBeans and their great service!
