Flying the AH-64 Apache Helicopter

Consult your local laws and ordinances before choosing a
location to fl y your aircraft.
We recommend fl ying your aircraft outside in calm winds
or inside a large gymnasium. Always avoid fl ying near
houses, trees, wires and buildings. You should also be
careful to avoid fl ying in areas where there are many
people, such as busy parks, schoolyards or soccer fi elds.
It is best to fl y from a smooth fl at surface as this will allow
the model to slide without tipping over. Keep the helicopter
approximately 2 ft (600mm) above the ground. Keep the
tail pointed toward you during initial fl ights to keep the
control orientation consistent. Releasing the stick in Stabil-
ity Mode will allow the helicopter to level itself. Activating
the Panic Recovery button will level the helicopter quickly.
If you become disoriented while in Stability Mode, slowly
lower the throttle stick to land softly.
During initial fl ights, only attempt takeoff, landing and
hovering in one spot.
Takeoff
NOTICE: If the main motor or tail motor do not startup
properly when throttle is fi rst applied, immediately return
the throttle to idle and try again. If the problem persists,
disconnect the fl ight battery, check for binding in the
gear train and ensure no wires have become entangled
within the gears.
Place the model onto a fl at, level surface free of obstacles
and walk back 30 feet (10 meters). Slowly increase the
throttle until the model is approximately 2 ft. (600mm)
off the ground and check the trim so the model fl ies as
desired. Once the trim is adjusted, begin fl ying the model.

Advanced Settings

The AH-64 Apache default settings are appropriate for most
users. We recommend fl ying with the default parameters
before making any adjustments.
Gain Parameters
1. Cyclic P Gain Adjustment (Default 100%)
Higher gain will result in greater stability. Setting the gain
too high may result in random twitches if your model
has an excessive level of vibration. High frequency
oscillations may also occur if the gain is set too high.
Lower gain will result in less stability. Too low of a value
may result in a less stable model particularly outdoors
in winds.
If you are located at a higher altitude or in a warmer
climate, higher gains may be benefi cial—the opposite
is true for lower altitude or colder climates.
EN
Hovering
Making small corrections on the transmitter, try to hold
the helicopter in one spot. If fl ying in calm winds, the
model should require almost no corrective inputs. After
moving the cyclic stick and returning it to center the
model should level itself. The model may continue to
move due to inertia. Move the cycle stick in the opposite
direction to stop the movement.
After you become comfortable hovering, you can progress
into fl ying the model to different locations, keeping the tail
pointed towards you at all times. You can also ascend and
descend using the throttle stick. Once you're comfortable
with these maneuvers, you can attempt fl ying with the tail
in different orientations. It is important to keep in mind
that the fl ight control inputs will rotate with the helicopter,
so always try to picture the control inputs relative to the
nose of the helicopter. For example, forward will always
drop the nose of the helicopter.

Low Voltage Cutoff (LVC)

LVC decreases the power to the motors when the battery
voltage gets low. When the motor power decreases and the
white LED on the top of the fuselage fl ashes quickly, land
the aircraft immediately and recharge the fl ight battery.
LVC does not prevent the battery from over-discharge
during storage.
NOTICE: Repeated fl ying to LVC will damage the battery.
Landing
To land, slowly decrease the throttle while in a low-level
hover. After landing, disconnect and remove the battery
from the aircraft after use to prevent trickle discharge. Fully
charge your battery before storing it. During storage, make
sure the battery charge does not fall below 3V per cell.
WARNING: To ensure your safety, always
disconnect the motor wires from the ESC
before performing the following steps. After you have
completed the adjustments, reconnect the motor wires
to the ESC before attempting to fl y the model.
2. Cyclic I Gain Adjustment (Default 100%)
Higher gain will result in the model remaining still, but
may cause low frequency oscillations if increased too far.
Lower gain will result in the model drifting slowly.
If you are located at a higher altitude or in a warmer
climate, higher gains may be benefi cial—the opposite
is true for lower altitude or colder climates.
3. Cyclic D Gain Adjustment (Default 100%)
Higher gain will improve the response rate of your inputs.
If the gain is raised too much, high frequency oscillations
may occur.
Lower gain will slow down the response to inputs.
