Installing a heading hold gyro into the Heli-Max AXE Mini
EP RTF will make the model easier to fly. The gyro will now
allow you to focus your concentration on the other controls
instead of constantly flying the tail.
We highly recommend using the optional Great Planes LiPo
11.1V 3s 15C battery (GPMP0815) for the best overall
performance. This battery provides a longer flight time and
higher power output in comparison to the stock NiMH battery.
Installing the Gyro
Use alcohol and a paper towel to remove any grease or
mold release agents on the gyro and helicopter frame. Apply
the double-sided foam mounting tape included with the gyro
to the bottom of the unit. Carefully align the gyro as shown
in the picture and mount the gyro onto the helicopter frame.
Solder a Micro Deans plug onto the motor wires of the C-12
ESC as shown. The negative (-) motor lead (blue wire)
connects to the male pin on the connector. This will be
connected to the tail motor in a later step.
It will be necessary to solder the E-Board and C-12 ESC to the
battery connector as shown above. If you decide to use the
Great Planes 910mAh LiPo battery (GPMP0815), we suggest
installing a Deans Ultra Male Plug onto the ESC and E-Board
to match the connector on the battery pack. The Deans Ultra
Plug will better handle the increased current draw of more
aggressive flight as your skill level advances.
Using wire cutters, remove the Deans Micro connector from
both battery input leads on the E-Board and the C-12 ESC.
Remove 1/4" [6mm] of wire insulation from both the positive
(+) and negative (-) leads of the C-12 ESC and E-Board.
Compare the battery pack connector to the ESC connector
and verify the polarity is correct before soldering. Twist and
solder together the positive battery lead from the C-12 ESC
and the positive lead from the E-Board. Slide the supplied
heat-shrink tubing (included with the Deans Ultra Plug) over
the wires and solder them to the Deans connector. Repeat
for the negative lead. Slide the heat-shrink tubing up the
wire to the plug. Use heat to shrink the tubing.
Disconnect the tail motor plug as shown above and connect
the plug directly into the blue and white motor wires on the
C-12 ESC.
Since the E-Board provides power to the receiver and
servos, the BEC in the C-12 ESC must be disabled.
