Charging Instructions
The T8 has a built in 1000mah 3.7v Battery. The built in USB-C charger will
charge your batteries by connecting the supplied USB-C cable to any suitable
USB power outlet. We suggest using a regular 2amp 5v USB power adapter.
Charge status and battery Level:
The 5 LEDS below the neck strap loop indicate the charging status. When the
LEDs light up from left to right the T8 is charging. Each of the 5 LEDs indicates
20% of the battery capacity. 5 LEDs shows 100% charge, 4 LEDs 80%, 3 LEDs
60%, 2 LEDs 40%, 1 LED 20%. When the radios power is low and the T8
requires charging all 5 battery status LEDs will flash at the same time. Please
recharge the batter before using the radio any further
Using your T8

now on. If the throttle or switches are not in the correct position the Power LED
will be RED. Please reset the switches to the correct position and move the
throttle to the lowest point. The Power LED will turn GREEN to indicate the radio
is now ready to use. To Turn off your T8 press and hold the power button until you
feel a vibration feedback and the radio will turn off. If the LED is RED when

Binding your T8
The T8 Uses a combination of Stick inputs and then pressing the Bind button to

Hold the LEFT gimbal Stick in the positions shown below then press the bind
button for more than 1 second to bind the required Protocol. The Power button will

Once a model or receiver is bound you can change between various models using
the Stick positions below and pressing the bind button for more than 1 second. The
Power button will blink blue to indicate the protocol is changing. There is no need
to put the model or receiver in bind mode again if it was successfully bound
previously.

Stick Top Right – D16 V1 LBT mode
Stick Bottom Left – D16 V2 FCC mode

Various different receivers and models will have different methods to place the
model or receiver in to bind mode. Please follow the instructions from the model or
receiver manufacturers user manual to initial the bind process.

A Note on input sensitivity:
If your craft feels too sensitive to input you may need to set up EXPO. EXPO is a
function to soften the stick feeling in the center of the stick movements. This can
help settle down a drone that is very sensitive to stick movements. This is handled
in the flight-controller firmware and varies depending on the flight controller you are
using and may be called EXPO or RC EXPO. Please refer to the setup guide of
your specific drone or flight controller to set EXPO to your desired setting on the
models flight control system.
