® ®
The Losi MTX Pro DSM ® radio system included with the Speed-T operates on 2.4GHz and provides 79 unique channels, which are
automatically selected when the transmitter and vehicle are turned on. The communication between the transmitter and receiver
begins in the few seconds after both are turned on.
They are bound together from the factory to uniquely operate together.
The Losi MTX Pro DSM radio system will not interfere with radio systems operating on legacy frequencies such as
27MHz or 75MHz, neither will you experience any overlapping interference from other 2.4GHZ systems.

Transmitter
The Losi Pro transmitter has several adjustments available to increase your enjoyment of the Speed-T vehicle.
1. Power switch – Turns the transmitter On and Off.
2. Dual rate – (ST.D/R) Adjusts how much the wheels can turn left/right in equal proportion.
3. Steering Trim – (ST.TRIM) Adjusts the “Hands Off” direction of the Speed-T.
4. Throttle Trim – (TH.TRIM) Fine adjustment for the throttle and brake center.
5. End Point Adjustment Pots – Adjusts the amount of servo movement for steering and throttle/brake (which should be set at
4:00 for proper ESC function).
From Left to Right they adjust the following:
• Right Steering
• Left Steering
• Throttle
• Brake
Using the End Point
Adjustments: All the adjust pots increase throw if turned clockwise and decrease throw turned counter-clockwise.
Steering: First set the steering trim so the Speed-T goes straight without touching the steering wheel. Lift the vehicle off the ground
and turn the steering wheel to the right. Using the enclosed mini screw driver to adjust the pot marked “right” back and forth stopping
when the wheels can turn to the right no further.
Repeat this process for the pot marked “left.”
Note: If you feel the vehicle turning more in one direction than the other you can use these pots to reduce the movement of
the side turning more.
The Throttle and Brake pots should be set just short of the full movement of each pot. Turn each to full and then back off slightly. If you
should be required to adjust throttle and brake endpoints, it is required to reset (calibrate) the transmitter and ESC. (See Page 18 for
more details.)
Receiver
There is no adjustment required of the receiver. Please note the different slots for connection.

There is Bind, channel one, channel two and auxiliary slots.
The bind slot is used to bind the transmitter to the receiver. The Losi MTX Pro DSM
® radio system uses a unique GUID ID to “bind” the
transmitter to each receiver. This bind process has been performed during assembly and is described should you replace the receiver
or during a trouble shooting exercise you be requested to rebind your transmitter and receiver.
Although the transmitter and receiver are set “bound” at the factory, below are the steps required to re-bind your transmitter and
receiver should the need arise.
