I'm currently installing servos and pushrods. Rudder and elevator are done. BUSA recommends placing them in front of the wing bolt down block for balance, but I figure with a big honking engine up front, radio battery, ignition battery and ignition module to place in the nose of the airplane, it wouldn't hurt to move the servos a couple of inches to the rear. I was having a real problem finding a way to work the throttle until I notice a machined throttle arm extension that came with the engine. Problem solved, but I will have to angle the pushrod to get the best movement on the throttle. Also, I'm going to have to pick up a ball link for the throttle pushrod.
