I'm having the same dilemma. I have the RadioWAVE 35% extra... essentially the same except the wing is foam and the servos aren't right together in the center... they're spread a little bit. Jtec Radiowave recommends 2x5945s or a single 8611 in each aileron... hopefully he's right!!!

I have a couple 8611As to use... they are supposed to put out over 300 oz of torque. I sure would like to know if your performance changes with a single 8611A or a single 5955... that would help me make up my mind. My thinking is that if a single 300 oz servo can do the job well, then the snaps would be BETTER than a 2 servo setup because of the reduced rolling inertia (since the outboard bay would be empty).

BTW... I have an 8611 (w/ new case) on each elevator and 2 8611As in a SWB self adjusting tray on the rudder... should be plenty of power.

Also... just out of curiosity... I am getting 31 degrees of elevator throw with 140% ATVs (couldn't use 150... I had to subtrim one servo). Are you finding this to be enough (I haven't flown yet)? These elevators are HUGE! I still can't decide if I want to do 3D with this plane or not... I have the rudder throw for sure, but I'm not sure if I want to move to more of an IMAC setup on the other surfaces or use 3D throws.
