Simple, affordable RC transmitter for many models

The T8FB is easy to get started with but offers features for more experienced users, and it suits both beginners and more advanced hobby projects with models such as aeroplanes, gliders, multirotors, RC cars, boats and robots.

Up to 2000 metres of range

The T8FB uses FHSS spread spectrum technology with 67-channel pseudorandom frequency hopping for a stable signal and good interference protection, and it is specified for about 2000 metres of range in the air in open conditions. Actual range varies with the model, installation, antenna position and surroundings.

High control precision

The T8FB has 4096 channel resolution and 0.25 µs precision per section, and the optimised circuit board layout gives low PWM jitter and a precise control feel, especially with small stick movements.

Parameter setting via app or USB

Parameters can be set via an Android or iOS app with Bluetooth, directly from your phone, or via a computer with a USB cable, and the firmware can be upgraded via USB for new features.

• The T8FB firmware program is compatible with Windows XP, Windows 7, Windows 8 and Windows 10
• The parameter app supports both Android and iOS
• The app language adapts automatically to your phone's language

Built-in real-time telemetry

The T8FB supports real-time feedback of transmitter voltage and RSSI, and with compatible receivers such as the R16F, R8FGH, R8FG or R7FG, model voltage can be shown in the mobile app for a better overview of the system status.

Programmable mix control

Channels 5 to 8 can be programmed for advanced settings and adapted to different functions and model types. On PIX-based systems, flight modes are controlled by two 3-position switches as standard.

Support for several model types

The T8FB adapts its layout to the selected mode, and the included R8EF receiver has a 210 mm antenna that also suits RC boats, where stable reception is important.

• Aeroplanes
• Gliders
• Multirotors
• RC cars
• RC boats
• Robots

R8EF receiver with PWM, SBUS and PPM

The included R8EF receiver supports PWM, SBUS and PPM and is flexible for different installations. With SBUS and PPM, channels 3 to 8 can output PWM at the same time, so the controls can be used for functions such as pan/tilt and landing gear.

Low power consumption

The T8FB uses a switched-mode power supply (SMPS) that keeps the operating current below 80 mA, and with a 3S 1800 mAh LiPo battery it is rated for more than 20 hours of use.

Wide operating voltage and flexible power supply

The T8FB has a wide operating voltage and a universal JST connector, and it works with several battery configurations.

• 4 x AA batteries
• 2S–4S LiPo battery
• 18650 lithium battery

Wide receiver compatibility

The T8FB comes with two R8EF receivers and is also compatible with several other RadioLink receivers.

• R8EF, standard receiver
• R16F
• R16SM
• R12F
• R8FM
• R8SM
• R8XM
• R8FGH
• R8FG
• R7FG
• R6FG
• R6F
• R4FGM

Good to know

Maximum range is tested in open areas without interference and can vary with the model, installation, antenna position, environment and signal conditions. Setting up via the app requires a compatible mobile device and Bluetooth; firmware upgrades and computer setup require a USB cable and compatible software; the simulator function requires a compatible receiver and a correct connection – always check the receiver, signal type, model type and channel settings before use.
