Well I just ordered one set to start. I want to fly a few flights and see what I think. If I need to shave some weight I'll go with lighter batteries, but I was thinking I would get a little more longevity and power out of the 30C - at least this is what was suggested by the local guys here.

I just put the plane up for a preliminary balance. It still needs the ESC and the Robart Hinges on the tail, and a little more hardware on the stab, but balance was right near the 185mm point!
