RADIO SYSTEM RULES 

• Always turn your transmitter on first and off last. This procedure 

will help to prevent your model from receiving stray signals 
from another transmitter, or other source, and running out of 
control. Your model has electronic fail-safes to prevent this type of 
malfunction, but the first, best defense against a runaway model is 
to always turn the transmitter on first and off last.

• Always use new or freshly charged batteries for the radio system.  

Weak batteries will limit the radio signal between the receiver and  
the transmitter.

 Loss of the radio signal can cause you to lose 

control of your model.

• Always turn on the transmitter before plugging in the battery.

• In order for the transmitter and receiver to bind to one another, 

the receiver in the model must be turned on within 20 seconds 
of turning on the transmitter. The transmitter LED will flash fast 
red, indicating a failure to link. If you miss it, simply turn off the 
transmitter and start over.

RADIO SYSTEM BASIC ADJUSTMENTS

Steering Trim

The steering trim knob located on the face of the 
transmitter adjusts the neutral (center) point of the 
steering channel. If your model pulls to the right or left 

when the steering wheel is centered, turn the knob until the model 
drives straight when the steering wheel is centered.

Channel Reversing
The TQ 2.4GHz transmitter has been programmed with the 
correct servo direction settings for your model and should not 
require adjustment.

 These instructions are for reference and 

troubleshooting only.

Reversing a channel reverses the direction of the corresponding 
servo. For example, if you turn the steering wheel to the right and 
the model turns left, Channel 1 would need to be reversed to correct 
the servo direction. Use the following procedures to reverse the 
steering and throttle channels, if necessary. 

Servo reversing should 

only be required if you accidentally reset the direction of a channel. 
Do not reverse the steering or throttle channels unless necessary.

Steering reversing procedure:

1.   Press and hold the SET button on the transmitter for two 

seconds. The status LED will flash green.

2.   Turn and hold the steering wheel to the full left or full right 

position (it does not matter which position you choose).

3.   While holding the steering wheel in position, press the SET 

button to reverse the channel. 

4.   The channel is now reversed. Confirm correct servo operation 

before running your model.

Throttle reversing procedure:
Note

: Throttle reversing is often times unnecessary on electric 

models, as issues with the throttle can usually be solved by 
reprogramming the speed control and/or verifying that the motor 
is wired correctly. Before attempting to reverse the throttle channel 
using the procedure below, you should first recalibrate the speed 
control. Refer to “XL-5 Setup Programming” on page 19.

Remember, always turn the 
transmitter on first and off 
last to avoid damage to your 
model. 

When rechargeable batteries 
begin to lose their charge, 
they will fade much faster 
than alkaline dry cells. Stop 
immediately at the first sign 
of weak batteries. Never turn 
the transmitter off when the 
battery pack is plugged 
in. The model could run out 
of control.

Always turn your

transmitter on first.

Turn on the model.
