7.2 Replacing ESC (For Repairs Only)
When replacing the MATRIX ESC, you must follow a specific procedure, otherwise
you may risk damage to the ESC wires, which may in turn short circuit the ESC and
Flight Controller.
Please remember to reapply Loctite when putting bolts and
screws back.
(1)
Make sure your battery is disconnected from the MATRIX.
(2)
Remove the screw that lock the MATRIX folding arm
(3)
Unscrew all the bolts from the top and bottom carbon.
(4)
Disconnect the three motor connectors between the motor and ESC. Prior to
disconnection, please mark down the color of motor wire and the motor you’re
replacing.
(5)
Remove the corresponding ESC signal connector from the flight controller. Prior
to disconnection and dismount the defective ESC.
(6)
Trace the ESC’s power supply wires back to the battery connector and disconnect
the corresponding ESC’s red and black bullet connectors.
(7)
Carefully remove the ESC from the bottom frame. Mark the old ESC for future
reference.
(8)
Replace the new ESC and connect the ESC signal connector to the flight
controller (for motor #1 ESC signal connector, it’s connected to M1 on the flight
controller. Motor #4 connector is connected to M4, etc…)
(9)
Reconnect the ESC’s power supply wire, the red and black bullet connectors
back to the battery connector.
(10)
Connect the motor connector back to the ESC.
(11)
Remount the bottom frame and mount the extension arm.
(12)
Please verify that the three motor wires are installed in the right positions by
doing a tie-down flight test described in Section 5.1 and pay special attention to
the motor that was replaced (look for the marking sticker on the extension arm).
Always make sure to motor direction is correct, Motor #1 and #3 are counter
clockwise, and motor #2 and #4 are clockwise.
(13)
If the motor direction is correct, go to the next step. If the motor direction is
incorrect, you may have made a mistake. Check your connections and make
necessary corrections. Two wires connected incorrectly will cause the motor to
spin in the wrong direction. Now tidy up the wires by pushing them back into the
extension arm. For reverse the motor direction, just swap 2 motor wires on the
ESC.
