Now this depends on what orientation you are going to mount the engine in... if you are going to put it sideways so the head sticks out the right side of the cowl and the muffler goes down, you will need to put all the radio gear in the left wingtip to couterbalance the engine cylinder. WES Tec micro servos should work well, although you will probably want to mount them in the left wingtip as well and run a pully setup to pull-pull style controls on the rudder and elevator through the root of the wing. Only use a 4.8 volt pack on these servos too, 6 volts will likely tear the hardpoints out of your elev and rudder on quick reflex moves with all the torque. Good luck, I am just getting my ripped apart airplane fixed and hope to be 3D'ing the wild .10 soon
