I'm using the connecting rod on mine. Not just for scale, but for weight and simplicity as well. The ailerons are quite small and this is no speed demon, so a single aileron servo per side should not have a problem at all as long as torque is in the 75+ oz. in. range. I'm going to use a 6 volt system with Hitec 475HB servos on all surfaces in mine. I've had great luck with these servos and they are about the most capable little servo available for the price. Unfortunately, I have not had much time to work on my plane and I will be travelling on business this week. All I've done is built the wings and installed the tail group and landing gear to the fuselage. Other than the totally unacceptable hinge slotting from the factory, everything so far has gone together great with super high quality components. I especially love the landing gear.
