I am using a separate servo for the nose gear. The wing LG will be connected to another servo mounted in the bottom/center of the wing. I'm still working on the best solution for smooth, catch free operation and steering. I have found that by putting the nose gear steering arm back to the other side as it came originally and not rotating it 180 deg. keeps the nose gear from hanging up on occasion. The only problem is now I don't have a straight line path down the side of the fuselage to the rudder servo arm. I'm working on trying to make good enough bends in the 2-56 control rod to go from one side of the fuselage to the other side and steer the nose gear properly. I still haven't settled on the type of connector I'll use on the nose gear steering arm.
