Why is my FMS Toy flight time so short?
If your FMS Toy aircraft has reduced flight time or seems underpowered, the issue might be a low flight battery charge. Completely recharge the flight battery. Alternatively, the flight battery might be damaged, in which case you should replace it, following all battery instructions.
What to do if FMS J-3 V3 Toy aircraft won't respond to throttle?
If your FMS Toy aircraft responds to controls other than the throttle, it could be due to the ESC not being armed. To solve this, lower the throttle stick and throttle trim to the lowest settings. Another possibility is that the throttle channel is reversed. If so, reverse the throttle channel on the transmitter.
Why does the motor on my FMS Toy pulse and then lose power?
If the motor power pulses and then loses power on your FMS Toy, this could be due to a loss of power to the aircraft. Land the aircraft immediately and recharge the flight battery. Another cause might be that the ESC uses a default soft Low Voltage Cutoff(LVC). If so, check the connection from the ESC to the receiver.
How to reduce propeller noise on FMS J-3 V3 Toy?
Excessive propeller noise or vibration in your FMS Toy could stem from several issues. It might be due to damaged spinner, propeller, motor, or motor mount, in which case you should replace the damaged parts. Alternatively, loose propeller and spinner parts could be the cause, so tighten the parts for the propeller adapter, propeller, and spinner. Finally, check if the propeller is installed backwards; if so, remove and install it correctly.
What to do if FMS J-3 V3 Toy control surface doesn't move?
If a control surface on your FMS Toy doesn't move or responds slowly, it could be due to damage to the control surface, control horn, linkage, or servo. Replace or repair any damaged parts and adjust the controls. Another possibility is damaged wires or loose connections, so check all connections for loose wiring.
Why does the motor on my FMS Toy lose power?
