Game Controller Style
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
 
T8S Specifications:
- Control distance: 2km (1.2mi)

- Built-in rechargeable battery with micro-USB port, good for 5 hours of standby time. Charges in 40 minutes from empty. LED is Red while charging, Blue when finished.
- Legal for all SPARC Robot Combat events! Upon loss of transmitter signal, the receiver outputs have a preset failsafe position for each channel.
- Model memory slots: Unlimited - Robot profiles are saved via the mobile app onto your phone, and can be loaded as needed via the app.
- FingerTech programs Mixing onto Channels 1 & 2 for single-stick robot drive applications.
- Channel variables and mixing can be programmed via the mobile app over bluetooth or via the included programming cable and PC software.

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.)

Basic Style
This simple 2.4GHz Transmitter is an excellent radio for robotics. Six channels lets you control all sorts of add-ons!
There is a knob and switch for both Channels 5 and 6. This allows you to set a motor speed or servo position, then switch it on to that preset position.
The right stick has spring return on both axes, the left stick has a ratchet for the up/down axis.
 
This radio is legal for all RFL Robot Combat events! Upon loss of transmitter signal, the receiver outputs all hold in "off" state. Most new motor controllers (like our tinyESCs) interpret this as motor-off and therefore pass the failsafe requirements. Servos will hold their last position, so make sure that does not pose a hazard in some way. No crystals to buy, and no need to worry about other radios interfering with your robot.

This transmitter has three programmable mixes, endpoint adjustment, subtrims, servo reverse, dual rates, and throttle curves! Incudes PC Cable for reprogramming channel variables and mixing.
 
Same transmitter as HobbyKing HK-T6A
Works with HK-T6RA V2 receivers. (Incuded)
Requires 8: AA Batteries (Not incuded)
Comes with Mixing on Channel 1 & 2 for single-stick robot drive applications.
