My Moki 2.10 had a 20x10 turning I believe 7400rpm if I remember right. 8800 on an 18x8 pretty good power. I cant imagine that wouldn't fly a 15 or so pound plane. I dont think I was quite getting 8800 with a Xoar 18x8 on my OS 1.60FX if I remember right. I'd sure give it a try. Just my thoughts for what its worth.
