Running a Bolly wood 22 x 10, peak rpms are 6600, can only richen up to 6550. I've got a 22 x 8 Bolly(cut down 23 x 8) wood on my other DA50 and it turns up around 7,000. Haven't actually tached it.

I've tried a MenzS 22 x 10 on it, but it would only swing it at 6100, and the Bolly wood 23 x 8 was 6300.

We cranked my buddy's DA50 up for the first time with a MenzS 22 x 10, and we could richen it up to 5100, so the prop isn't the problem......
