After assembly and transmitter setup, confirm that the control surfaces are
centered. The model must be powered up and bound to the transmitter in AS3X
mode, with the throttle left at zero. When enabled, SAFE mode is active at power
up. AS3X mode is activated when the throttle is raised above 25% for the first time
after being powered on. It is normal for the control surfaces to respond to aircraft
movement if the aircraft is in AS3X or SAFE modes.
1. Verify the trims and subtrims on your transmitter are zero
2. Power up the model in AS3X mode and leave the throttle at zero
NOTICE: Be aware of the pushrod bottoming out in the clevis. Do not thread the
pushrod too far into the clevis or the pushrod will damage the clevis.
3. Center the rudder with the vertical stabilizer. If adjustment is required, turn
the clevis on the linkage to change the length between the servo arm and the
control horn until the rudder is straight.
4. Center the elevator by aligning the elevator with the horizontal stabilizer. If
adjustment is required, adjust the linkage length as in step 3 as necessary.
Control Surface Centering
• Turn the linkage clockwise
or counterclockwise until the
control surface is centered.
• Attach the linkage to the
servo arm or control horn
after adjustment

Battery Installation and ESC Arming
Battery Selection
A 3S 2200mAh LiPo battery is required. The Spektrum 2200mAh 11.1V 3S 30C
IC3 LiPo battery (SPMX22003S30) is recommended. Refer to the Optional Parts
List for other recommended batteries. If using a battery other than those listed,
the battery should be within the range of capacity, dimensions and weight of the
Spektrum Li-Po battery packs to fit in the fuselage. Be sure the model balances at
the recommended CG before flying.
1. Lower the throttle and throttle trim to the lowest settings. Power on the
transmitter, then wait 5 seconds.
2. Carefully lift the canopy hatch (A) to remove.
3. Install a fully charged battery B) and secure it into place using the hook an
loop strap (C). See the Adjusting the Center of Gravity instructions for more
information.
4. Connect the battery to the ESC. If you have not completed the bind sequence,
do so at this time as outlined in this manual.
CAUTION: Always keep hands away from the propellers. When armed, the
motor will turn the propellers in response to any throttle movement.
5. Keep the aircraft immobile and away from wind or the system will not initialize.
• The motor will emit a series of rising tones when the battery is connected,
and then tones indicating the number of cells connected.
• An LED will light on the receiver when it is initialized
6. Reinstall the battery hatch.
ESC Tones
If the ESC sounds a continuous double beep after the flight battery is connected,
recharge or replace the battery.
ESC Error Tones Tone Meaning Possible problem
Continuous slow single tones Abnormal throttle signal
Transmitter and receiver not bound
Throttle lead damaged or not plugged into receiver
Throttle lead plugged into receiver backward
Continuous rapid single tones
Throttle signal not at low
position
Throttle stick not at low position
Throttle travel reduced below 100%
Throttle reversed
Throttle trim raised
Continuous double tones
Battery voltage is beyond
acceptable range
Verify battery is a 11.1V 3-cell LiPo
Verify battery is fully charged
