I don't like Y pushrods in general, so I'm setting my GP Spacewalker with dual elevator servos. My experiences have been that a dual elevator setup can actually be simpler to install and setup. You can match up the control throws very easily, especially if you have a computer radio.

I haven't decided whether to mount the elevator servos up front or near the tail. It will depend on how the plane balances out with the G23 I'm putting on the nose, in place of the Magnum 1.20 4stroke originally fitted.

Two $25 servos typically have much more torque than one $50 servo.
