CAUTION: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle movement.
1. Lower the transmitter throttle stick and turn on throttle cut. With the throttle
cut on, throttle input from the throttle stick is deactivated. This safety feature
ensures any accidental bump of the throttle stick will not activate the motor
while the ight battery is connected.
IMPORTANT: If you connect the battery while the throttle is not at its lowest
position, the ESC will not arm. Reduce throttle to the lowest setting for the
ESC to arm.
2. Power on the transmitter, and wait at least 5 seconds before proceeding.
3. Lift from the front of the hatch, near the propeller, to remove the battery
hatch.
4. Secure the ight battery in the battery compartment using the hook and
loop material so the aircraft is balanced at the correct center of gravity
(CG). See the Center of Gravity section for information on measuring the CG.
5. Connect the ight battery to the ESC connector, noting proper polarity.
6. Replace the battery hatch, ensuring the battery wires are not caught in-
between the hatch and the fuselage.
7. Keep the aircraft immobile while the SAFE system initializes.
8. After the SAFE system initializes, the control surfaces will move back and
forth, then come to neutral to indicate the SAFE system has initialized and
is ready to operate.
IMPORTANT: If the aircraft is moved and does not complete initialization
within approximately 30 seconds, disconnect and reconnect the ight
battery to re-initialize the system.
IMPORTANT: AS3X technology in Experienced Mode is not active until you
advance the throttle past 25%. Once it is active, the control surfaces may
move on the aircraft. This is normal. The AS3X technology will remain active
until the ESC is disconnected.
CAUTION: Always disconnect the Li-Po ight battery from the aircraft
receiver when not ying to avoid over-discharging the battery.
