Battery Installation and ESC Arming
Battery Selection
We recommend a 22.2V 6S 3200mAh 50C LiPo battery with IC5 connector. If using
a different battery, the battery should be of similar capacity, dimensions and weight
to t in the fuselage. Always be sure the model balances at the recommended CG
with the battery chosen.
1. Lower the throttle to the lowest setting.
2. Power on the transmitter and wait 5 seconds.
3. Apply the loop side (soft side) of the hook and loop tape to the bottom of the
battery.
4. Slide the canopy latch back and lift the back of the canopy to remove it.
5. Install the fully charged battery in the battery compartment as shown.
See the Adjusting the Center of Gravity instructions for more information.
6. Secure the ight battery with the hook and loop strap.
7. Connect the ESC to the battery power lead IC5 connector, noting the correct
polarity. The ESC will emit two sets of audible tones in succession indicating the
programming status.
• The rst set of tones indicates the number of cells in the connected LiPo
battery pack. 6 rapid tones = 6
• The second set of tones indicates the brake status. One tone indicates brake
"ON" and two tones indicates brake "OFF".
NOTICE: Connecting the battery to the ESC with incorrect polarity will damage
the ESC and void the warranty.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The
aircraft's ESC protects the ight battery from over-discharge using Low Voltage
Cutoff (LVC). Once the battery discharges to 3V per cell, the LVC will reduce the
power to the motor in order to leave adequate power to the receiver and servos to
land the airplane.
When the motor power decreases, land the aircraft immediately and replace or
recharge the ight battery.
Center of Gravity
WARNING: Install the battery but do not connect it to the ESC while
checking the CG. Personal injury may result.
The CG location is 80–90mm behind the leading edge at the wing root. Always
check the CG location with model inverted, and the landing gear down.
The CG location is adjusted by moving the battery pack forward or backward in the
battery compartment.
Control Horn and Servo Arm Settings
The table to the right shows the factory settings for the control horns and servo
arms. Fly the aircraft at factory settings before making changes.
NOTICE: If control throws are changed from the factory settings, the AR631
gain values may need to be adjusted. Refer to the Spektrum AR631 manual for
adjustment of gain values.
After ying, you may choose to adjust the linkage positions for the desired control
response. See the table to the right.

8. The ESC is now ready for use.*
9. Reinstall the canopy hatch by sliding the hatch pin latch back on the fuselage.
Ensure the hatch pin engages.
* While additional programming of the ESC is not necessary to operate your aircraft,
programming options are available. Visit www.horizonhobby.com for complete
instructions on programming the included ESC.
Always disconnect and remove the Li-Po battery from the aircraft after each
ight. Charge your Li-Po battery to about half capacity before storage. Make sure
the battery charge does not fall below 3V per cell. Failure to unplug a connected
battery will result in trickle discharge.
For your rst ights, set your transmitter timer or a stopwatch to 3 minutes. Adjust
your timer for longer or shorter ights once you have own the model.
NOTICE: Repeated ying to LVC will damage the battery.
