Mounting and Connection
A1
Before you Begin
Fly the helicopter without Ace Waypoint and make sure that the helicopter works properly without any autopilot assistance. To
complete this step, you will need a tail gyro instead of Ace Waypoint system. This is a good time to isolate and resolve unwanted
vibrations. IT IS IMPORTANT THAT YOU SHOULD NOT SKIP THIS STEP.
A2
Mount the devices on your helicopter
 IMU

Where? The IMU is best positioned near the helicopter’s center of gravity, where
vibration is relatively low.

What orientation? Orient the IMU such that the arrow marked on the above
surface of the IMU faces the sky and points directly forward, backward, left or
right. The sides of the IMU should be precisely parallel to the helicopter body.
DO NOT MOUNT THE IMU UPSIDE-DOWN.

How? Use double-sided foam tape for secured installation.
1
Check the double-sided foam tape or Velcro regularly to ensure that the
IMU is securely positioned.
2
DO NOT cover the ventilation holes, keep them unobstructed.
3
The IMU module is NOT water-proof or oil-proof.
 GPS & Compass Module (GPS)

Where? Mount it on the tail boom, between the
rotor-head and the tail-rotor. The compass is
sensitive to magnetic interference, so position the
module at least 20 cm from servos and 30 cm from
electric motors or gasoline (petrol) engines. The
GPS is sensitive to vibration interference, so position
the module at least 10 cm from the tail rotor. The
GPS should not be close to the main rotor head
because rotor blades can interfere with GPS satellite
signal, the farther from the center of the rotor disk,
the better.

What Orientation? The DJI logo marked on the
GPS should face the sky, with the orientation arrow
pointing directly forward. The GPS is packaged with
a special indication line for mounting for the first
time. The LED status indicators should face the tail
rotor.
1
If you are uncertain whether materials near the GPS are magnetic or not, you can use a compass or magnet to check it.
2
GPS mounting-support hardware is included in the Ace Waypoint package. If however you prefer to use your own GPS
mount, please make sure that the mount material is NOT magnetic.
 Main Controller (MC)
 Where? There is no orientation requirement for the MC. Maintain at least a 20-centimeter-distance between the MC and the
engine or motor. Choose a mounting location where as shorter servo extension wires are needed as possible. This helps reduce
the risks of electronic interference. Please also make sure the USB port is accessible when installing the MC so as to facilitate
software configuration.
After choosing a location to mount the MC, it is recommended that you DO NOT mount the MC until all wirings and software
configurations are completed.
