Manual and firmware download
The T8 comes factory installed with special T8 firmware for D8 and D16 use. No firmware updates are required for this radio. Simply charge, Bind and go fly! Visit www.radiomasterrc.com to learn about optional hardware accessories to convert your T8 in to a T8 Pro!
Remote control overview
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 power of the radio is low and the T8 requires charging all 5 battery status LEDs will flash at the same time. Please recharge the battery before using the radio any further
Using your T8
Press and hold the Power button until you feel vibration feedback. The radio is 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 vibration feedback and the radio will turn off. If the LED is RED when turning off disconnect power to your model first.
Quick Guide to Understanding the Power Button LED colors.
GREEN: Radio is starting up or turned on and working normally.
RED on start: A switch(s) or the throttle must be moved to the default position.
RED on shut down: The model or receiver is still connected, disconnect power to the model to complete the shutdown cycle of the radio.
The T8 has the following settings by default and is ready to set up with the firmware of your flight controller or receiver up to 8 channels. The default channel order is AETR, please set it accordingly in your flight controller software.
CH5 2 Position Switch SA
CH6 3 Position Switch SB

Binding your T8
The T8 Uses a combination of Stick inputs and then pressing the Bind button to bind to one of the following protocols: D8 / D16 v1 FCC / D16 v1 LBT / D16 v2 FCC / D16 v2 LBT
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 blink blue to indicate binding is in progress.
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 Center – D8 Mode|
|Stick Top Left – D16 V1 FCC mode|
|Stick Top Right – D16 V1 LBT mode|
|Stick Bottom Left – D16 V2 FCC mode|
|Stick Bottom Right – D16 V2 LBT 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 manufacturer’s user manual to initial the binding 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 maybe 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 model’s flight control system.
