The servos should be a direct transplant, as long as they are a sub-micro, which I think is what you needed for the MUS anyway, probably HS55's. They are recommending the 450 so that should tranfer over fine, but I am having a hard time convincing myself not to get the 480 From what I have read, the aerobatic performance and speed are very comparable to the MUS, I will better answer that once they start shipping planes . As far as the wheels are concerned, I am looking at some larger replacement for all three, most of the time I fly in parks and grass is all you have to land on, so the wheel pants will probably have to go.
