I just finished mine and had an O.S. 160FX laying around so I threw it in. Have a APC 18x6W prop on it but haven't had the time to maiden it yet. All Servos are high torgue metal gears except for the rudder which is super high torque. Plane seems to balance okay on the recommended CG but I'm not real happy about tying the ailerons together with rods. Four servos would have been much better. Anything you guys can tell me about maidening this thing would be appreciated.
