Did an all new servo tray. Rudder servo in the center, with each elevator servo on both sides. I used a mini servo for the throttle--made a separate servo tray for it too. Plane flies very nicely, and will hover. Very nice plane. Do a search for the GB Decathlon--you should find plenty of threads on it. The only bad thing about the plane is its flying wires. THEY NEED TO BE REPLACED OR STRENGTHENED!!! They are very weak. Don't bother trying to fly the plane with the wing struts on. THey WILL flutter themselves off.
