Joe,

If mostly flying imac you will be fine. Heck Mike McConville even used 1 per side on his plane he flew at the Masters and Tucson Shootout, so I feel you are fine even with 3d. I personally like the feel of 2 but this is just for the 3d aspect of it. If you have any more questions please feel free to ask.

Sorry about not responding right away. I have been down in Ohio working on my new Quique 40% Yak This airplane should be fun to set up 3 servos per aileron 2 per elevator and 4 on the rudder. Thank Heaven for matchboxes.

Andrew
