Heli-Max HMXM1011 - Manual (Page 2)

gyro to calibrate its sensor and confirm that it is
operating correctly (indicated by the LED on the
gyro blinking regularly with a single flash).
❏ 2. Quickly rotate the nose of the helicopter to
the right and observe the direction that the arm
on the tail rotor servo responds. The arm on the
tail rotor servo should rotate in a direction that will
make the tail rotor turn the nose of the helicopter
to the left. If it does not, move the switch on the
bottom of the gyro to the other position.
❏ 3. Turn off the gyro. Turn on the gyro. Wait three
seconds. Perform step 2 again to confirm that the
gyro is responding in the correct direction.
Caution: If the gyro is operating backwards, the
helicopter will pirouette uncontrollably at a high rate
of speed.
SET THE GYRO’S SENSITIVITY
This step is only a starting point to setting the
gyro’s sensitivity rates. Once at the flying field, the
rates will have to be fine-tuned by flight testing.
❏ A. Determine which switch on the transmitter is
the one that operates the “gyro” channel (usually
channel 5). From now on this will be referred to as
the “gyro” switch and is the switch that will be
used to select between the two gyro sensitivity
settings.
Set the ATV’s so that when the gyro switch is
away from you, the gyro is in the more sensitive
setting for hovering. For aerobatics, the switch will
be flipped to the other position, toward you.
❏ B. With the gyro switch away from you, set the
ATV to 60%.
❏ C. Flip the gyro switch to the other position
(toward you). Set the ATV to 30%.
FLIGHT TESTING
Now that the gyro’s sensitivity rates have been
tentatively set up on the workbench, the gyro must
be fine-tuned by flight testing.
❏ 1. If you are a beginner and are not yet able to
break into forward flight, for now you’ll just have to
estimate the gyro sensitivity required. 60% is a
good starting point. Beginners also do not yet
have a requirement for two different sensitivity
settings and should set the ATV’s in both gyro switch
positions to 60%.
❏ 2. When you take the heli outside, allow it to sit
for a few minutes before turning the radio on. This
will allow the gyro to become acclimated to the
temperature and is necessary due to the temporary
effect the temperature change can have on a
piezo gyro.
❏ 3. Move the gyro switch to the “hovering” (more
sensitive) position.
❏ 4. Turn on the transmitter and receiver. Wait
three seconds. Confirm the operation of the gyro.
Start the engine and lift the helicopter into a hover.
Beginners who are not yet able to hover should
increase power until the helicopter becomes light
on its landing gear (or training gear), yet does not
leave the ground.
❏ 5. Give a tail input to test the response. If the
tail responds faster than you prefer or is not
stable, the gyro is not sensitive enough. Land the
helicopter and increase the ATV. If the tail hunts
or wags back and forth, or does not respond as
quickly as you would like, the gyro is too sensitive.
Land the helicopter and reduce the ATV. Make
adjustments in small increments. Continue hovering
and adjusting the ATV until the helicopter handles
the way you prefer.
If you are a beginner and are not yet into forward
flight and aerobatics, you are done. But you
should read step 6 anyway!
❏ 6. Adjust the gyro for forward flight and
aerobatics. The setting you achieved in a hover
may work for general sport flying, but fast forward
flight and aerobatics may require a less sensitive
gain setting. To test this, flip the gyro switch to the
other position. Fly the helicopter around and try a
few aerobatic maneuvers. As in a hover, if the tail
wags or bounces back and forth, the sensitivity is
too high. Land the helicopter and reduce the ATV
for that switch position. If more gyro sensitivity is
required, increase the ATV. Continue to fly your
helicopter and adjust the ATV as required.
