Let me chime in on the prop as well.

I've flown G-62's (albeit, all modified by Ralph) on several planes, and there's no question for MY TASTES, that the Xoar props have outperformed everything else. At one point, I'd been through props from no less than 9 manufactures.

FWIW, I get 6800+ on a Xoar 23x8 with one of Ralph's engines. not sure what the performance difference would be between a modified and unmodified G-62, but that's a decent starting point, I think.
