FMS EDF Jet 80mm F-86 Sabre flaps not work

When we observe the aircraft structure, it's not difficult to see that the movement of flaps, wings, etc., is achieved through servos and connecting rods. If you find that the flaps or wings are not moving, our initial judgment is that it is caused by the servos or the connecting rods. Several possibilities may cause servo failure:

1. Transmitter setting issues: Check the transmitter settings.
2. Check if the CH6 channel interface and wiring are normal. CH6 is the flap interface, the red wire is positive, the brown wire is negative, and the white or yellow wire is the signal wire.
3. Servo quality issues: A crash can damage the servos, requiring a replacement. If it's a new product with quality issues, please contact customer service for a replacement.
4. ESC malfunction: This part has a very low probability of failure.
5. Low battery power.
6. Reflex parameter adjustment errors.
