Using Reverse: While driving, 
push the throttle trigger 
forward to apply brakes. 
Once stopped, return the 
throttle trigger to neutral. 
Push the throttle trigger 
forward again to engage 
proportional reverse. 

USING THE RADIO SYSTEM

The TQi Radio System has been pre-adjusted at the factory. The 
adjustment should be checked before running the model in case of 
movement during shipping. Here’s how:

1.  Turn the transmitter switch on. The status LED on the transmitter 

should be solid green (not flashing).

2. 

Elevate the model on a block or a stand so that all the tires are 
off the ground.

 Make sure your hands are clear of the moving 

parts of the model.

3.  Plug the battery pack in the model into the speed control. 

4.

 

The on/off switch is integrated into the speed control. Press 
and release the EZ-Set button on the speed control to turn the 
model on. The LED will shine RED or GREEN (see note below). To 
turn the VXL-3s off, press the set button until the LED turns off.  

Note

: If the LED shines green after the speed control is turned 

on, Low-Voltage Detection is activated. This may cause poor 
performance from NiMH battery packs. Make sure to turn the 
Low-Voltage Detection on when using LiPo batteries. 

Never 

use LiPo batteries while Low-Voltage Detection is turned off. 

See page 18 for more information.

5.  Turn the steering wheel on the transmitter back and forth and 

check for rapid operation of the steering servo. Also, check that 
the steering mechanism is not loose or binding. If the steering 
operates slowly, check for weak batteries.

6.  When looking down at the 

model, the front wheels 
should be pointing straight 
ahead. If the wheels are 
turned slightly to the left 
or right, turn off TSM (see 
page 17) and slowly adjust 
the steering trim control 
on the transmitter until they are pointing straight ahead; then, 
return the multi-function knob to the desired TSM setting.

7.  Gently operate the throttle trigger to ensure that you have 

forward and reverse operation, and that the motor stops when 
the throttle trigger is at neutral. 

Warning

Do not apply full 

throttle in forward or reverse while the model is elevated.

8.  Once adjustments are made, turn off the receiver on your model, 

followed by the hand-held transmitter.

Range-Testing the Radio System

Before each running session with your model, you should range-test 
your radio system to ensure that it operates properly.

1.   Turn on the radio system and check its operation as described in 

the previous section.

2.   Have a friend hold the model. Make sure hands and clothing are 

clear of the wheels and other moving parts on the model.

3.   Walk away from the model with the transmitter until you reach 

the farthest distance you plan to operate the model.

4.   Operate the controls on the transmitter once again to be sure 

that the model responds correctly. 

5.

 

  Do not attempt to operate the model if there is any problem 

with the radio system or any external interference with your 
radio signal at your location. 

Higher Speeds Require Greater Distance

The faster you  drive your model, the more quickly it will near the 
limit of radio range. At 60mph, a model can cover 88 feet every 
second! It’s a thrill, but use caution to keep your model in range. If 
you want to see your model achieve its maximum speed, it is best 
to position yourself in the middle of the car’s running area, not 
the far end, so you drive the car towards and past your position. In 
addition to maximizing the radio’s range, this technique will keep 
your model closer to you, making it easier to see and control. 

No matter how fast or far you drive your model, always leave 
adequate space between you, the model, and others. Never drive 
directly toward yourself or others. 

TQi Binding Instructions

For proper operation, the transmitter and receiver must be
electronically “bound.” 

This has been done for you at the factory.

Should you ever need to re-bind the system or bind to an additional 
transmitter or receiver, follow these instructions. 

Note

: The receiver 

must be connected to a 4.8-6.0v (nominal) power source for 
binding, and the transmitter and receiver must be within 5 feet of 
each other.
1.   Press and hold the transmitter’s SET button as you switch the 

transmitter on. The transmitter’s LED will flash red slowly.  
Release the SET button.

2.   Press and hold the receiver’s LINK button as you switch on  

the speed control (by pressing the EZ-Set button). Release the 
LINK button.

3.   When the transmitter and receiver’s LEDs turn solid green, the 

system is bound and ready for use. Confirm that the steering 
and throttle operate properly before driving your model.
