Adjusting the Center of Gravity (CG)
The CG location is 175mm back from the nose, which was determined with the recommended battery at the front of
the battery tray.
Transmitter and Receiver Binding
Binding is the process of linking your transmitter and receiver. You need to `bind’ your chosen SpektrumTM DSM2®/
DSMX® technology-equipped aircraft transmitter to the receiver for proper operation.
Binding Procedure
1. Refer to your transmitter manual for instruction on binding the transmitter to a receiver.
2. Ensure the flight battery is not connected to the aircraft.
3. Depending on your transmitter, either power off the transmitter or ensure the RF signal is off.
4. Connect the flight battery to the Aircraft. The LEDs will begin flashing slowly, turn the aircraft upside down until
the LED does a slow blue flash, indicating the Ultrix is in bind mode.
5. Make sure the transmitter controls are at neutral and the throttle and throttle trim are in a low position.
6. Place the transmitter in bind mode. Refer to your transmitter manual for binding instructions.
7. After 5-10 seconds, the receiver will connect and the motor will arm. If you encounter problems refer to the
Troubleshooting Guide at the back of the manual.
For subsequent flights, power on the transmitter for 5 seconds before connecting the flight battery.
