• Bolt down the motor and solder the cable again following the colours that you noted down.
Attention!
If the colours of the connecting cables are swapped, the rotating direction of the motors will change. This
will cause the model to malfunction! As a precaution, compare the configuration of the other motors with
that of the replaced motor.
• Insert the driver board in its clamp once again, check to see if the flat cable is sitting correctly as a connector to the
flight control and mount the upper part of the grid frame.
Should you wish to replace several motors, you should carry out the individual steps in sequence for each
motor.
d) Replacing a Radial Arm
Damaged radial arms can be replaced. Carry out the steps as described under „Replacing a Motor“. When you have
removed the motor from the damaged radial arm, simply secure the motor to the new radial arm and carry out the
steps as described.
For replacing the radial arm, remove the upper part of the grid frame. When removing the radial arm, turn this slightly
and remove from the grid frame.
e) Replacing the Complete Frame
If the frame is broken after crashing but the electronics are still in working condition, it is possible to replace the
complete frame.
For this, simply remove the upper and lower enclosures and the upper part of the grid frame, then remove the motors
as described under the point „replacing a motor“ and insert the motors in the new radial arms. Remove the remaining
electronics (flight control and 2x driver board) from the clamp and place in the new grid frames. Then mount the new
radial arms in the new grid frames.
