This servo tray is as thin as the servo itself and holds it precisely in position. The frame is bonded into the wing with epoxy. Two screws and a pair of clips hold the servo in the frame. The system makes flex free linkages possible and also allows you to replace a damaged servo within seconds.
Sold as pairs.
The following servos fit this frame:
Graupner DS 3288, JR378 and JR DS 171
