Select Technology
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The aircraft’s ESC protects the fl ight
battery from over-discharge using Low Voltage Cutoff (LVC). Before the battery charge decreases too much, LVC removes
power supplied to the motor. Power to the motor quickly decreases and increases, showing that some battery power is
reserved for fl ight control and safe landing.
When the motor power pulses, land the aircraft immediately and recharge the fl ight battery.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. During storage, make
sure the battery charge does not fall below 3V per cell.
TIP:
Due to the quiet nature of the aircraft, you may not hear the pulsing of the motor.
For your fi rst fl ights, set your transmitter timer or a stopwatch to 3 minutes. Adjust your timer for longer or shorter fl ights
once you have fl own the aircraft. Flights of 4 minutes or more are achievable if using proper throttle management.
NOTICE:
Repeated fl ying to LVC will damage the battery.

When SAFE Select is activated, bank and pitch limitations keep you from over-controlling the aircraft. Additionally, by
releasing the controls in the event you lose orientation, SAFE Select will keep the aircraft level.
To activate SAFE
®
Select, fl ip the Gear channel switch to position 0. Return the Gear switch to position 1 to turn OFF
SAFE Select and fl y with just the assistance of AS3X
®
technology.
If you become disoriented or the aircraft is in a confusing attitude, fl ip the Gear switch to position 0 and release the
sticks. With the aileron, elevator and rudder sticks in the neutral position, SAFE Select will automatically keep the
airplane in a straight and level attitude.
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 fl ying, 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 rotor, intake and exhaust tube 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.
