PlaneJim,
The splitting up of the aileron servos does not necessarily give you a higher roll rate. It does due to the linkage set up at the aileron, but it may not be that noticable. I am not a torque rod fan, and almost always do away with them, even on something as simple as a trainer. Ailerons are less likely to "give" at speed, and there's no wearing out the aileron hole, where it enters (torque rod set-up). I've had to land a couple of planes after the servo failed (torque rod) and I can tell ya it is a little tricky banking with the left hand, while controlling altitude with the right!
It also allows you a "backup" should one servo fail!
Not everybody will agree with this, but it is my preference.
And yeah, dem DragonLady's float in nice, eh?
