Well...I think I might end up with the 58...not totally sure yet though...thanks for the responses thus far...

As far as the servos, I guess I should return these and get 5945's...its frustrating to find conflicting information like that..and I bought these during the 20% off a servocity, now I miss out on that. I am still kind of suprised that these servos can't handle those ailerons on the ultimate...they aren't that big of a control surface, plus you got the work of 'roll' in the plane is split up betwee four control surfaces each with its own servo (as compared to other similar size planes that have only 2 ailerons, so the 'load' should be around 1/2, but whatever, I will return them)
