Range Test

HOLD

WARNING: Do not perform this or any other equipment test with the

propeller installed on the aircraft. Serious injury or property damage could

result from the motor starting inadvertently.

WARNING: While holding the aircraft during the range test, always keep

body parts and loose items away from the motor. Failure to do so could

cause personal injury.

Before each ﬂ ying session, and especially with a new model, you should perform

a range check. If you have the BNF aircraft, refer to your transmitter manual to

perform a range check of your system.

The RTF included DXe transmitter incorporates a range check mode to reduce the

output power of the transmitter. Follow the directions below to enter range check

mode for the DXe transmitter:

1. Power on the transmitter for 5 seconds or more with the throttle stick and trim

low. Plug in the aircraft battery and keep the aircraft immobile for 5seconds.

2. Face the model with the transmitter in your normal ﬂ ying position.

3. Toggle (back and forth = 1 toggle) the HI/LO Rate switch rapidly 4 times and

then press and hold the bind button. The transmitter LEDs will ﬂ ash and the

alarm will sound. The system is in range check mode. Do not let go of the bind

button until you are ﬁ nished with the range check.

IMPORTANT: You must hold the BIND/Panic button during the entire range check

process. Releasing the button will exit the range check mode.

4. With the radio system powered on and the model restrained on the ground,

stand 28meters (90 feet) away from the model.

TIP: In some aircraft, when the model is placed on the ground, the antenna(s) can

be within inches of the ground. Close proximity of the antenna(s) to the ground

can reduce the effectiveness of the range check. If you experience issues during

the range check, restrain the model on a non-conductive stand or table up to 2ft

(60cm) above the ground, then range check the system again.

5. Move the transmitter rudder, elevator, aileron and throttle controls to ensure

they operate smoothly at 28 meters (90 feet).

6. If control issues exist, do not attempt to ﬂ y. Refer to the contact table at the

end of the this manual to contact Horizon Hobby product support. Also, see the

Spektrum website for more information.

7. When the range check is successfully completed, release the bind button to exit

range check mode.

CAUTION: Due to reduced output power of the transmitter, NEVER attempt

to ﬂ y while the transmitter is in range check mode. Loss of control will

occur.
