Steering Trim 

The electronic steering trim located on the face 
of the transmitter adjusts the neutral (center) 
point of the steering channel. 

Multi-Function Knob

The Multi-Function knob can be programmed to 
control a variety of functions. From the factory, 

the Multi-Function knob controls steering sensitivity, also known as 
exponential or “expo.” When the knob is turned counterclockwise 
all the way to the left (default position), expo is off and steering 
sensitivity will be linear (the most commonly used setting). Turning 
the knob clockwise will “add expo” and decrease the steering 
sensitivity in the initial range of steering wheel travel left or right from 
center. For more detail on steering exponential, refer to page 13.

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.  Turn on the receiver switch in the model. The switch is located 

on the rear shock tower.

3.  Position the Jato 3.3 so that its front wheels are off the ground. 
4.  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 receiver batteries.

5.  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, slowly adjust 
the steering trim control on the 
transmitter until they are pointing straight ahead. 

6.  Operate the throttle trigger on the transmitter and check for 

rapid operation of the throttle servo. When the throttle trigger 
is pulled back, the carburetor should open. When the throttle 
trigger is pushed all the way forward, the brake should lock.

7.  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 with the engine off.
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 truck’s running 
area, not the far end, so you drive the truck towards and past 
your position. In addition to maximizing the radio’s range, this 

When the engine is running, 
do not use the throttle trim 
on the transmitter to adjust 
the engine idle speed. 
Always use the idle speed 
adjustment screw (see page 
15) on the carburetor.

Applying The Decals

The main decals for your model 
have been applied at the factory. 
The decals are printed on self-
adhesive clear mylar and are 
die-cut for easy removal. Use a 
hobby knife to lift the corner of a 
decal and lift it from the backing. 
To apply the decals, place one 
end down, hold the other end up, 

and gradually smooth the decal 
down with your finger as you 
go. This will prevent air bubbles. 
Placing both ends of the decal 
down and then trying to smooth 
it out will result in air pockets.
