could result from the motor starting inadvertently.
1. Set the flight mode switch to Experienced mode (position 2).
2. Keep the throttle at zero and place the model on level ground away from
obstacles.
3. Move the sticks on the transmitter as described in the table to ensure the

An aircraft with the correct CG is balanced for safe, stable flight.The aircraft CG
and weight are based on having the recommended battery installed.
The CG location is 67-70mm back from the leading edge of the wing at the
root and is marked on the bottom of the wing with a raised “CG”. Balance the
aircraft on your fingertips at the raised marks.
Adjust the battery position as needed get the aircraft to balance correctly.
• If the nose goes down, move the flight battery back until the aircraft balances.
• If the nose goes up, move the flight battery forward until the aircraft balances.
When in intermediate and experienced modes, if the aircraft CG is too far
forward (nose heavy), up elevator is required to fly level at 50%-60% power. If
the aircraft CG is too far aft (tail heavy), down elevator is required to fly level.
In Beginner mode the aircraft is not affected. The SAFE system controls the
aircraft attitude.
