Heli-Max HMXE04 - Manual (Page 2)

❏
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. Carefully lift up
the plastic tab on the C-12 ESC connector, remove the red pin
from the plug, and fold it back over the wire. Wrap a piece of
electrical tape or heat-shrink tubing around the connector pin
and wire. Plug the C-12 ESC into the GY240 gyro.
❏
Remove the orange wire from the receiver and plug the
GY240 into the same position. Verify the black wire (-) on the
connector is towards the outside edge of the receiver. Now
plug the orange connector into the next available position on
the receiver (channel 5), and align it with the column of white
wires on the other connectors.
❏
Use two tie straps to attach the gyro wires to the frame. Bundle
the wires and ESC together at the front of the helicopter.
❏
On the gyro, set the “AVCS” switch to “ON” and set
the “DIR” switch to “REV”. Set the gain to 60% using the
adjustment dial on the gyro. If necessary, adjust the gain to
match your fl ying style or desired setup. The typical range of
gain is 50% to 75%.
Review your work and verify that none of the wires can
get caught in the main rotor gear or the swash plate. The
helicopter is now ready for the test fl ight.
FLIGHT INITIALIZATION
If this is your fi rst time fl ying a heading hold gyro, be sure
to take your time and become accustomed to the new gyro
before jumping into your normal fl ying routine.
Turn on the transmitter, center the tail rotor trim tab, extend
the antenna, and verify the idle up switch is “OFF” (toward
the back of the transmitter). Connect the fl ight battery and
allow the gyro 10 seconds to initialize. The helicopter and tail
rotor stick must remain still during this process.
ARMING THE TAIL ESC
The tail motor ESC must be armed before each fl ight. The
best time to do this is after you place the helicopter on the
ground before taking off.
You will hear three beeps from the tail ESC once the gyro has
initiated. Carefully apply full right tail rotor and you will hear
4 beeps. Apply full left tail rotor and you will hear another set
of beeps. The tail ESC and motor are now armed and you
are ready to fl y. If you need to pick up the helicopter, fi rmly
hold onto the main frame since the tail motor could operate
at any time. You can hold full left tail rotor on the transmitter
to prevent this from occurring.
FLYING
If the tail wants to drift slowly due to wind gusts, your gain
may be set too low. Increase the gain a small amount and
see if performance improves.
If the tail has a tendency to oscillate from left to right,
your gain may be set too high. Reduce the gain and see if
performance improves.
