What to do if FMS Twin 70mm Su-27 aircraft throttle not working?
If your FMS Toy aircraft isn't responding to the throttle but other controls are working, it could be that the ESC is not armed. Try lowering the throttle stick and throttle trim to the lowest settings. Another possible cause is that the throttle channel is reversed; in this case, reverse the throttle channel on the transmitter.
Why is my FMS Twin 70mm Su-27 flight time so short?
If you're experiencing reduced flight time or your FMS Toy aircraft feels underpowered, the most likely cause is a low flight battery charge. Completely recharge the flight battery. Alternatively, the flight battery may be damaged, so replace the flight battery, following all instructions.
How to reduce propeller noise on FMS Toy?
Excessive propeller noise or vibration in your FMS Toy can stem from several issues. Check for a damaged spinner, propeller, motor, or motor mount and replace any damaged parts. Also, inspect for loose propeller and spinner parts, tightening them as needed on the propeller adapter, propeller, and spinner. Finally, ensure the propeller is installed correctly; if it's backward, remove and reinstall it properly.
Why are the controls reversed on my FMS Twin 70mm Su-27 Toy?
If the controls on your FMS Toy are reversed, the channels are likely reversed in the transmitter. Perform the control direction test and adjust the controls for both the aircraft and the transmitter.
What to do if FMS Toy control surface is not moving?
If a control surface on your FMS Toy doesn't move or responds slowly to control inputs, there may be damage to the control surface, control horn, linkage, or servo. Replace or repair any damaged parts and adjust the controls. Another possibility is damaged wiring or loose connections; inspect the connections for loose wiring.
Why does my FMS Toy motor pulse and then lose power?
If your FMS Toy motor pulses and then loses power, the ESC is likely using the default soft Low Voltage Cutoff (LVC). Land the aircraft immediately and recharge the flight battery.
Why does the FMS Toy motor lose power?
If the motor on your FMS Toy loses power, it indicates a loss of power to the aircraft. Check the batteries, transmitter, receiver, ESC, motor, and wiring for any damage and replace components as needed.
