1.2 „Binding“ the receiver
With the binding process the receiver is coupled to the transmitter.
Turn on the transmitter, then connect the power of receiver keeping the receiver
„BIND“ button till the light turn on GREEN which means the binding is successful.
After that, it’s unnecessary to bind again.
•Caution: making sure that the RX and TX within one meter, and around 10
meters no similar device.
•If the LED is flashing, showing the binding failure, please do again as above
indication.

2.1 Characteristics of system
•3 channels End Point Adjustment.
•Support dual rate function for the STEERING.
•Sub-trim for THROTTLE channel and STEERING channel.
•Model names can use up to 5 letters and numbers, so that easily understood
names can be set. A model memory with different fine setups can be created
by using the model copy function. Sixteen models can be added.
•Brake mixing for large cars (BRAKE)
oBrake mixing of the front and rear wheels of 1/5GP and other large cars
can be adjusted independently.
oAnti-skid braking system (A.B.S) This function applies the brakes so
that the tires of gasoline engine cars, etc. do not lose their grip on the
road even when braking at corners.
•SPEED
oTH-SPEED: Sudden trigger operation on a slippery road surface will
only cause the tires to spin and the model to not accelerate smoothly.
By setting the throttle speed function, operation can be performed
smoothly and easily. It also suppresses battery consumption.
oST-SPEED: When you sense that the steering servo is too fast, etc.,
the servo operating speed (direction that suppresses the maximum
speed) can be adjusted.
•Auto-Start funktion (ATS)
oA pre-set throttle position, less than full throttle, to be used for the initial
acceleration off the line without having wheel spin. When the trigger is
released, auto-start is turned off and throttle operates normally again.
•TIMER: The TC-3 has two timers: Down_Timer and UP_Timer.
•Digital trim function: The current trim position is displayed on the LCD screen.

•Quick steering operation will cause momentary under steering, loss of speed, of
spinning. This function is effective in such cases.
•This function limits the maximum speed of the steering servo. (Delay function)
•The steering speed when the steering wheel is operated (TURN direction) and
returned (RETN direction) can be independently set.
•If the steering wheel is turned slower than the set speed, the steering servo is not
affected.
Throttle Speed
•Sudden throttle trigger operation on a slippery road only causes the wheels to
spin and the vehicle cannot accelerate smoothly. Setting the throttle speed
function reduces wasteful battery consumption while at the same time
permitting smooth, enjoyable operation.
•Throttle servo (amp) operation is delayed so that the drive wheels will not spin
even if the throttle trigger is operated more than necessary. This delay function
is not performed when the throttle trigger is returned and at brake operation.

19
ATS Automatic Start
When the throttle trigger is set to full throttle simultaneously with starting when the
track is slippery, the car wheels will spin and the car will not accelerate smoothly.
When the Start function is activated, merely operating the throttle trigger slowly
causes the throttle servo to automatically switch from the set throttle position to a
preset point so that the tires do no lose their grip and the car accelerates smoothly.
•When the throttle trigger is moved to the preset trigger position (TRI), the
throttle servo moves to the preset position (POS).
•When the throttle trigger is operated slowly so that the wheels will not spin, the
car automatically accelerates to the set speed.
•This function is effective only for the first throttle trigger operation at starting.
This function has to be activated before every start.
•When the throttle trigger is returned slightly, the Start function is automatically
deactivated and the set returns to normal throttle trigger operation.
