8-channel RC set 2.4GHz FHSS with gimbal sticks, 2 switches, 2 rotary encoders, reverse switch for channels 1-4. Receiver R8EF. When connected to a PC or smartphone (Android), it can be programmed like a conventional computer transmitter.

T8FB BT is an 8-channel transmitter for hobby model builders, which you can also use as a classic 8-channel transmitter with gimbal sticks, 2 switches, 2 rotary encoders, and a reverse switch for channels 1-4.
If you connect it to a control program on your PC or an application on a smartphone with Android or iOS, it transforms into an intelligent computer transmitter, allowing you to set basic functions such as servo reverse, mixers for flying wings and delta wings. It even has two freely programmable mixers (in the Android 4 application). Thanks to these functions, it allows the control of all common models:

• Acro models
• Gliders
• Multicopters
• Ground vehicles and ships.

It features a practical casing that fits very well in the hand, with a long-proven, ergonomic arrangement of the controls.

Controls:
The main functions are controlled by precise gimbal sticks with adjustable centering springs. It is possible to convert the throttle from left to right. This allows you to choose stick modes 1-4. The digital trims have an audible signal for the step sequence and the center position. They are slightly eccentrically arranged and easy to reach. Additional channels can be controlled by the two rotary encoders on the top of the transmitter, and two switches (one with 3 and one with 2 positions) can serve as channel switches or for switching program functions on/off (after setting up on a PC or smartphone). The controls are assignable (with PC or smartphone).

Transmitter Power Supply:
T8FB BT can be powered by a variety of different batteries/rechargeable batteries:

• 4 alkaline batteries in the included holder
• NiMH battery pack with 4 cells (AA size, mignon cells)
• 2-3 LiPo or Li-Ion cell pack.

When the transmitter is connected to a PC or smartphone, the battery voltage is displayed, and a low voltage warning is adjustable. We recommend a 4.8V NiMH battery pack with low self-discharge (Eneloop) for this transmitter.

Transmission system: 
T8FB BT uses FHSS transmission with frequency hopping, which guarantees a long range, reliability, and interference immunity. It does not allow telemetry transmission.

Software:
When connected to a PC or smartphone, you get a variety of transmitter setting options. You can retrieve existing settings from the transmitter, change them as needed, and reload them into the transmitter, save them on a PC or smartphone, or load stored settings into the transmitter. The control program or application has four menus:

• SERVOMonitor for servo travel display of all channels.
• BASIC menu for setting the reverse switch function (for both directions independently of the center), subtrim, failsafe, and servo speed.
• ADVANCED menu for setting dual-rate throws, ATTITUDE function (up to 6-position switch for drone flight modes), mixers for delta and flying wings.
• SYSTEM menu for assigning channels 5-8, gimbal stick modes 1-4, setting the audible low voltage warning for the transmitter battery, and two freely programmable mixers (4 in the Android application, where you can also set a 7-point throttle curve and both/expo throws for channels 1-4).

Micro USB socket 
(at the bottom of the transmitter) is used for updating the firmware and programming the transmitter with a PC.

Bluetooth module 
is used for programming the transmitter with a smartphone or tablet with the Android or iOS operating system.

Trainer-student socket 
is used to control models via a dual control system with two Radiolink transmitters connected via a trainer-student cable. T8FB BT can be used as a student transmitter. In addition to the classic cable (1RL0058), a wireless connection can also be used via a receiver with a PPM output, which is connected to the trainer-student socket of the trainer transmitter via a special adapter (1RL0056). The receiver is paired with the student transmitter.

Transmitter strap: 
You can attach a strap to the T8FB BT transmitter and wear it around your neck (strap not included).
