Holes are cut for standard servos. For elev and rudder, you have one servo each - mounted in tail. You'll need one 6" servo ext and one 12" (I think that's what I used, if I remember correctly)

You could modify to to use 2 elev servos in the tail and then move the rudder servo to the fuse and make it pull-pull, like on the Laser 3D.

I used futaba 9206 on the rudder and elev of mine and Hitec 5625mg on the ailerons. however I might switch them to the 225mg.

balance was right on with battery ahead of the tank (because you'll mount the tank on CG with YS63, there's room in the front of the plane, in the space that would normally hold the tank)
