Testing Failsafe
Secure the aircraft on the ground and remove the propellers. Test Failsafe
by turning the transmitter off and noting how the receiver drives the control
surfaces.
Receiver Power Only
• With SmartSafe or Preset Failsafe, when the receiver only is turned on (no
transmitter signal is present), the throttle channel has no output, to avoid
operating or arming the electronic speed control.
• All other channels have no output until the receiver has linked to the transmitter.

Range Testing

Before each fl ying session and especially with a new model, it is important to
perform a range check. All Spektrum aircraft transmitters incorporate a range
testing system which, when activated, reduces the output power, allowing
a range check.
1. With the model restrained on the ground, stand 30 paces (approx. 90
feet/28 meters) away from the model.
2. Face the model with the transmitter in your normal fl ying position and place
your transmitter into range check mode.
3. You should have total control of the model with the button depressed at 30
paces (90 feet/28 meters).
4. If control issues exist, contact the appropriate product support department.
