SAFE

Select Technology
Disabling and Enabling SAFE Select
By default, the SAFE Select function of your UMX aircraft is
enabled and assigned to the Gear channel switch (channel
5). If you do not wish to have access to SAFE Select while
flying, you can choose to disable SAFE Select functionality.
AS3X will still be active when SAFE Select is disabled.
IMPORTANT:
Before attempting to disable or enable SAFE
Select, ensure the aileron, elevator, rudder, throttle and
gear channels are all on high rate with the travel set to
100%. Turn throttle hold OFF if it is programmed in the
transmitter.
CAUTION:
Keep all body parts clear of the
propeller, and keep the aircraft securely
restrained in case of accidental throttle
activation.
1. Power on the transmitter.
2. Power on the aircraft.
3. Hold both transmitter sticks to the inside bottom
corners and toggle the Gear switch 5 times
(1 toggle = full up and down). The control surfaces of
the aircraft will move, indicating SAFE Select has been
enabled or disabled.
Repeat the process again to re-enable or disable SAFE
Select.
DXe, and DXS Transmitters
Switch A is the FMODE switch on the these transmitters,
and the switch needs to be toggled between position 0
and 2 when disabling/enabling SAFE Select.

Mode 1 and 2 Transmitters
The P-51D Voodoo has two flight modes controlled by
Channel 5, SAFE and AS3X. Switch A is the Spektrum default
for channel 5. Position 0 is SAFE, Position 1 is AS3X only.
When flying in SAFE mode, the aircraft will return to level
flight any time the aileron and elevator controls are at
neutral. Applying aileron or elevator control will cause
the airplane to bank, climb or dive. The amount the stick
is moved will determine the attitude the airplane flies.
Holding full control will push the aircraft to the pre-
determined bank and pitch limits, but it will not go past
those angles.
When flying in SAFE mode, it is normal to hold the control
stick deflected with moderate aileron input when flying
through a turn. To fly smoothly with SAFE, avoid making
frequent control changes and don’t attempt to correct for
minor deviations. Holding deliberate control inputs will
command the aircraft to fly at a specific angle, and the
model will make all corrections to maintain that flight
attitude.
Return the elevator and aileron controls to neutral before
switching from SAFE mode to AS3X mode. If you do not
neutralize controls when switching into AS3X mode, the
control inputs used for SAFE mode will be excessive for
AS3X mode and the aircraft will react immediately.

Smart Technology Telemetry
This aircraft includes Spektrum Smart Technology in the
receiver, which can provide telemetry information like
battery voltage. To take advantage of Smart Technology,
you will need a compatible transmitter. A firmware update
for your transmitter may be required.
To View Smart Telemetry:
1. Begin with the transmitter bound to the receiver
2. Power on the transmitter.
3. Power on the aircraft.
4. The Smart Logo appears under the battery logo on
the home page. A signal bar appears in the top left
corner of the screen.
5. Scroll past the servo monitor to view Smart
technology screens.
For more information about compatible transmitters,
firmware updates, and how to use the Smart Technology
on your transmitter, visit www.SpektrumRC.com.
