I´m currently restoring a KF2 with Rotax 582 gray head with 3.00 gearbox and my next step is to replace the old GCS propeller. I have emailed a few dealers but the all recommend different size props and i would highly appreciate any advice or help you guys can give me.


Theese are the answer i got divided in prop brand

Luga or NR prop:
SL106-1750 (three-blade), 1750 is about 68"

Ivopro:
They only recommend 2 blade 72" prop because of my 3.00 gearbox

Bollypropellers:
70" three blade

Warpdrive:
4-blade 64” Ultra-Prop II

The Luga and Warp Ultra is around 600 eur and the others are double the price.
