Thanks for the pics illustrating what I was saying Dan. Nice setup. And I recommend that plastic pushrod you used over the metal cable, as mentioned before.

His problem with resistance in the throttle setup may be due to sharp bends in the throttle cable in the fuel tank area, as the throttle servo is on the port side of the airplane, and the throttle arm on the carb is on the starboard side. He probably has two sharp 90 degree bends in the cable in the fuel tank area. A better setup would be to have the throttle cable cross over in the receiver area and get to the other side with two gentle 45 degree bends.
