Solution
• Check the batteries in the transmitter (polarity) or replace them.
• Check the function switch.
• Replace the batteries in the transmitter.
• USB port amperage is too low.
• Replace the helicopter battery.
• Check the helicopter battery charge level.
• Check that the mechanical drive parts can move freely.
• Repeat the power on procedure.
• Check the flight battery charge level.
• Check that the mechanical drive parts can move freely.
• Check the rotor blades.
• Repeat the power on procedure.
• Avoid interference from other 2.4 GHz transmitters.
• Trim the model (see Figure 14).
• Repeat the power on procedure and ensure that you do not move or
rotate the helicopter.
• Check that the tail rotor runs smoothly and functions properly.
• Calibrate position sensors.
• Check the rotor blades.
• Recharge the helicopter battery (ensure that the USB port has suf-
ficient current).
• The helicopter battery is faulty.
• The mechanical parts cannot move freely.
• Calibrate position sensors.
• Trim the helicopter.
• Unfavourable flight conditions (draught).
• The rotors are defective.
• The motor shaft of the main or tail rotor is bent.
• Rotor blades are overtightened.
