Flight Battery

Voltage Indicator

Flight Battery Voltage Indicator

The included DXS transmitter is equipped with a flight battery voltage

indicator feature that works with compatible Smart technology receivers, flight

controllers and telemetry-capable ESCs. This Smart technology feature gives a

visual representation of the approximate flight battery voltage/power remaining

via the four LED indicators on the transmitter.

• When the battery is fully charged, all four LEDs glow solid.
• When the throttle is increased, the voltage of the battery drops, causing the

LEDs to indicate less voltage, via fewer LEDs glowing solid or flashing. The

useable capacity of the battery remains.

• When the throttle is decreased, the load on the battery decreases and the

voltage of the battery increases, indicated by more LEDs glowing solid or

flashing. Over time less of the useable capacity of the battery remains and

less power is available, indicated by fewer LEDs glowing solid or flashing.

• When the last LED begins to flash, the flight battery low voltage alarm on

the transmitter sounds before the low voltage cutoff function is triggered in

the aircraft ESC (see the Flying section for a description of the low voltage

cutoff function). The flight battery low voltage alarm sounds for 25 seconds.

If the throttle is lowered and the flight battery voltage recovers because

enough useable capacity remains in the flight battery, the alarm will stop

before 25 seconds. In either case, land the aircraft as soon as practical

after the alarm sounds.

To reset the flight battery low voltage warning:

1. After landing, disconnect the flight battery from the aircraft for at least

15 seconds, or until the flight battery voltage indicator LEDs on the DXS

transmitter go out.

2. Connect a fully charged battery to the aircraft. The flight battery voltage

indicator resets prior to the next flight.

CAUTION:

Always keep hands away from the propeller. When armed,

the motor will turn the propeller in response to any throttle movement.

1. Lower the transmitter throttle stick and turn on throttle cut (switch H, position 1).

With the throttle cut on, throttle input from the throttle stick is deactivated. This

safety feature ensures any accidental bump of the throttle stick will not activate

the motor while the flight battery is connected.

IMPORTANT:

If you connect the battery while the throttle is not at its lowest

position, the ESC will not arm. Reduce throttle to the lowest setting for the

ESC to arm.
2. Power on the transmitter, and wait at least 5 seconds before proceeding.
3. Rest the aircraft on a flat surface with the landing gear facing up.
4. Turn the battery compartment latch and remove the battery hatch.
5. Secure the flight battery in the battery compartment using the hook and

loop straps so the aircraft is balanced at the correct center of gravity (CG).

See the Center of Gravity section for information on measuring the CG.

6. Connect the flight battery to the ESC connector, noting proper polarity.
7. Replace the battery hatch, locking it in place with the battery compartment

latch.

8. Set the aircraft upright on its landing gear. Keep the aircraft immobile while

the SAFE system initializes.

9. After the SAFE system initializes, the control surfaces will move back and

forth, then come to neutral to indicate the SAFE system has initialized and

is ready to operate.

IMPORTANT:

If the aircraft is moved and does not complete initialization

within approximately 30 seconds, disconnect and reconnect the flight

battery to re-initialize the system.

IMPORTANT:

AS3X technology in Experienced Mode is not active until you
