Wow, I didn't even know George was doing an Ultimate. Looks like the GWS EPS300C on the nose. Can't tell the gearing of course. I wish I could fly half as well as George...

Yes, the Razor 400 will work. You just have to gear it at a lower ratio as it's kv (revolutions per volt/per minute) is lower than the 350. I think the "C" gearing would work well.

Looks like an asy way to route the channels. I'll have to try that with my dremmel.

That last video was with the brushless set-up
