I'm at a CG of about 5.25" with an OS 91Surpass and my question is, are you guys getting pretty bad pitch and roll coupling with your UCDs? Is this a product of my CG? I have it programmed out for knife edge flight, but with extreme input for a knife edge loop, it gets pretty hard to make it look respectable.

Also, on knife edge spin, it'll do a slow spin, it really won't tighten up, is this a CG issue as well. I've got an 1800mah pack and receiver all the way to the back of the radio bay, I'm already marginally powered for knife edge loops, how are you guys getting your CG back without adding weight?

Also, I'm using a 15x4W and I've tried a 14*6, do you guys see any other options? It'll pull out of hover and all, I'm just looking for free power, overall I'm very pleased with this motor though, very consistent and user friendly. Thanks,
Eric
