Center of Gravity (CG)
The CG location is measured from the leading edge of the wing at the root.
This CG location has been determined with the recommended Li-Po battery
(EFLB32003S30) installed to the front edge of the battery tray.
AS3X Control Direction Test
This test ensures that the AS3X
®
control system is functioning properly.
Assemble the aircraft and bind your transmitter to the receiver before
performing this test.
1. Raise the throttle just above 25%, then lower the throttle to activate AS3X.
CAUTION: Keep all body parts, hair and loose clothing away from a
moving propeller, as these items could become entangled.
2. Move the entire aircraft as shown and ensure the control surfaces move in
the direction indicated in the graphic. If the control surfaces do not respond
as shown, do not fly the aircraft. Refer to the receiver manual for more
information.
Once the AS3X system is active, control surfaces may move rapidly. This is
normal. AS3X remains active until the battery is disconnected.

Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge.
The ESC protects the flight battery from over-discharge using Low Voltage Cut-
off (LVC). Before the battery charge decreases too much, LVC removes power
supplied to the motor. Power to the motor pulses, showing that some battery
power is reserved for flight control and safe landing.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent
trickle discharge. Charge your Li-Po battery to about half capacity before stor-
age. During storage, make sure the battery charge does not fall below 3V per
cell. LVC does not prevent the battery from over-discharge during storage.
NOTICE: Repeated flying to LVC will damage the battery.
Tip: Monitor your aircraft battery’s voltage before and after flying by using a
Li-Po Cell Voltage Checker (EFLA111, sold separately).
