Fitting a Whirlwind prop. I already miss my wooden 2 blader.

But my wooden prop only gives me about 65 knts at 5000 on my Rotax 912. As lovely as it looks, the props primary purpose is not aesthetics, so out it goes.

 

The Whirlwind prop is 3 blades and carbon fibre, the exact opposite, in my mind, of a beautiful prop. But it came off a Savage Cub. So it's already set up for a similar airframe to mine. Should be pretty close to optimised. I don't care if it isn't right now, it's gotta have better performance than the wooden one ☺️

 

Oh, just to add to the fugly factor, the spinner it came with is too big forl my cowl. So sans le nez it is!

I can redline it! So on takeoff I have to fly like the big boys and do quite a bit of fiddling with the throttle. No WOT with the wooden wonder! So- 5800rpm take off run, then flaps up, then back it off to 5400rpm then when leveling out, down to 5000.

now you have a ground adjustable you will get it dialled in.

Can't be bothered. It's already dialled in for a similar plane, so that will be near enough for me 😀
