RadioLink T8S-BT 2.4GHz 8-Channel Radio Set

The RadioLink T8S transmitter is a lightweight and comfortable gamepad-style transmitter, with 8 channels of control all easily within reach.

- Programmable per-channel failsafes, endpoint adjustment, subtrims, servo reverse, dual rates, throttle curves, and 4 custom programmable mixes.

- Along with the two thumb sticks, there is a three-way (on-off-on) switch on each top side, a push button on the top right, and a rotary knob on the left side.  These allow all sorts of special programming, such a dual rates for controlled driving vs turbo mode, or setting a weapon motor speed or servo position that can be switched on/off to that preset position.

- The right stick has spring return on both axes, the left stick has a ratchet for the up/down axis. If you prefer both axes to be spring-return, the radio includes the pieces needed for converting.

Includes:

- R8EF receiver
- Programming/charge micro USB cable
- Spring return kit for tank drive
- Instruction manual booklet
- FingerTech lanyard for holding the transmitter

Downloads:

- Download the Drivers, Configuration Files, and Quickstart Guide (zip file). Open its READ_ME_FIRST.txt for installation and programming instructions.
(Note: When loading any saved configuration file via PC, click into tab ADVANCE1 and set ATTITUDE to CH: OFF. A software bug always sets this value back to Ch5. We have asked the manufacturer to resolve this.)

Binding Instructions: 
If you power on your robot but the receiver only gives a slow red flash, it means there is no valid paired transmitter being detected.
1. To bind a receiver to a transmitter, first power off the robot and transmitter
2. Bring the transmitter and the receiver close to each other (about 50cm / 20in).
3. Power on the T8S.
4. Power on the R8EF. Its red LED will start flashing slowly.
5. Press the Binding Button on the side of the receiver until the LED begins flashing quickly then release, the binding process will begin.
6. When the LED stops flashing and turns to constant on, binding is complete. If it fails, the LED will keep flashing slowly so repeat the above steps to try again.
7. When binding is complete, you can turn on your transmitter and robot and the receiver's red light should be on solid with the tinyESCs blinking to indicate valid signal. (Assuming you are using tinyESCs.)
