Compact handheld transmitter for many models
The T8S is a small and handy handheld RC transmitter whose low weight, detachable joysticks and compact format make it easy to carry. It can be used with helicopters, airplanes, gliders, multirotors, RC cars, boats and robots, among others.
Up to 2000 meters of range
The T8S uses FHSS spread spectrum with 67-channel pseudorandom frequency hopping for stable signal transmission and good interference protection. It is specified for about 2000 meters of control range in the air under open, interference-free conditions.
High precision in control
The T8S has 4096 channel resolution and 0.25 µs precision per section, and the optimized circuit board layout gives low PWM Jitter and a stable control signal. This gives a more precise control feel, especially in models where small inputs and even response are important.
Parameter setup via app and USB upgrade
Parameters can be set via an Android or iOS app with a Bluetooth connection, directly from your phone. The firmware can be upgraded via USB, and according to the documentation an unlimited number of model settings can be stored.
- The parameter app supports both Android and iOS
- The app language adapts to the phone’s language
- The software for firmware upgrade and parameter setup supports Windows XP, Windows 7, Windows 8, Windows 10 and Windows 11
Built-in real-time telemetry
The T8S supports real-time feedback of transmitter voltage and RSSI, and together with compatible receivers such as the R16F, R8FGH, R8FG or R7FG, model voltage can be shown in the mobile app.
Four programmable Mix functions
Channels 5 to 8 can be programmed, and the T8S supports standard Mixes such as aileron-to-elevator Mix and flap-to-aileron Mix for fixed-wing or V-tail models. The four programmable Mix functions also make the transmitter useful for cars, boats, engineering vehicles and twin-motor models.
Support for several model types
The T8S can be used with many model types and switches its layout depending on the selected mode. The included R8EF receiver has a 210 mm antenna and is also well suited to RC boats where stable reception is important.
- Helicopters
- Airplanes
- Gliders
- Multirotors
- RC cars
- RC boats
- Robots
R8EF receiver with PWM, SBUS and PPM
The included R8EF receiver supports PWM, SBUS and PPM, which makes it flexible and reduces the need for extra cables or signal converters. When using SBUS and PPM, channels 3 to 8 can simultaneously output the corresponding PWM signals, for example for pan/tilt and landing gear.
Ergonomic and portable design
The T8S has a compact and ergonomic design with low weight, and the detachable joysticks can be adapted to the user’s hands and control habits for more comfortable longer sessions.
USB charging and built-in battery
The built-in 1S 900 mAh lithium battery is charged via a computer or phone charger with a USB cable, and below 3.7 V the green battery indicator flashes with a warning sound. The T8S has low power consumption of less than 150 mA and about 5 hours of usage time at full charge.
Broad receiver compatibility
The T8S comes with two R8EF receivers and is also compatible with several other RadioLink receivers.

- R16F
- R16SM
- R12F
- R8XM
- R8FM

Good to know
The actual range can vary with the model, installation, antenna placement, environment and signal conditions. Parameter setup requires a compatible mobile device and a Bluetooth connection, firmware upgrade requires a USB cable and compatible software, and the simulator function requires a compatible receiver and a correct connection – always check the receiver, signal type, model type and channel settings before use, and charge the lithium battery according to the manufacturer’s instructions with a suitable USB power source.
