BOX CONTENTS

QUICK START

Please read the entire manual to gain a full understanding of the LMT vehicle. The LMT comes assembled without electronics, use this manual to guide you through the electronics installation, fine-tuning the setup and maintenance.

1.  Read the safety precautions found in this manual.
2.  Install the motor, receiver, ESC and steering servo.*
3.  Connect the steering drag link to the servo saver.
4.  Route the servo and ESC wires and connect them to the receiver.
5.  Charge a battery for the vehicle. Refer to your charger manual for important charging warnings and instructions for battery charging.
6.  Install the fully charged battery in the vehicle.
7. Bind the receiver to your transmitter. Verify the controls are centered.
8.  Mount the servo saver to the servo with steering centered.
9.  Adjust your servo direction and travel as needed in your transmitter.
10.  Calibrate your ESC.
11.  Install the cover over the receiver.
12.  Check the steering and throttle control directions. Reverse the servo in your transmitter if the steering is reversed. Reverse the motor with the wire connections or ESC settings if the throttle is backward.
13.  Install the wheels.
14.  Drive your vehicle.
15.  Disconnect the battery when done driving.

INSTALL THE MOTOR

1.  Install the pinion gear on your motor. Place the pinion on the end of the motor shaft so the set screw is located over the flat on the shaft.

2.  Position it so the teeth line up with the spur gear and secure the pinion by tightening the set screw.

3.  Install your motor. There is a pair of mounting holes for each pinion gear size, be sure to select the mounting position that matches your pinion gear selection.
   CAUTION: It is important you select the correct motor mounting holes for your pinion gear selection. The gear mesh is pre-set with each pair of motor mounting holes corresponding to the pinion gear. Selecting the wrong mounting holes is likely to cause damage to the spur gear on your LMT when you attempt to apply power.
   Refer to your motor manual for more information. If you select an optional 15 or 16 tooth pinion gear, the motor will have to be installed first, and then the pinion gear. The following drawing shows the correct motor mounting holes to use for the included 14 tooth pinion gear.
   

4.  Install the gearbox cover.
   

INSTALL THE STEERING SERVO AND ESC

1. Install your servo using the included servo mounting screws. Ensure the servo is securely mounted to the servo mount. Don’t connect the servo saver at this time.
2.  Run the servo wire into the receiver box.

1.  Install your ESC. Connect the motor wires to the ESC. Refer to your ESC manual for more information.
2.  Run the throttle lead to the receiver box.
3.  If you plan to power any auxiliary options such as lights, run the leads into the receiver box.

INSTALL THE RECEIVER

1. Install your receiver with double sided tape or hook and loop material.
   

2.  Insert the servo and ESC connectors in the appropriate ports on the receiver.

3.  Connect the steering drag link to the servo saver (not connected to the servo yet).
   

4.  Verify the steering servo is centered and traveling in the correct direction

5.  With the steering linkage centered, connect the servo saver to the servo and install the screw that was included with your servo.
   

6.  Check the steering direction, travel, and fine tune the center point with your transmitter settings. See your transmitter manual for more information.

INSTALL THE WHEELS
Use the included hardware to mount the wheels to the vehicle.

CONTROL DIRECTION TEST

Place the vehicle on a stand supporting the chassis so the wheels are off the ground during the steering and throttle tests. Verify all the controls work correctly before turning it on with the wheels on the ground.

1. Move the steering left to right and observe the response at the wheels. If the wheels are moving backward to your command, reverse the steering control in your transmitter.
2.  Apply a small amount of throttle and observe how the wheels respond. If the wheels turn backward with forward throttle, either change the motor wiring to reverse the motor, or change the settings in the ESC. Refer to your ESC manual for more details.

DRIVING PRECAUTIONS

•  Maintain sight of the vehicle at all times.
•  Routinely inspect the vehicle for loose wheel hardware.
•  Routinely inspect the steering assembly for any loose hardware. Driving the vehicle off-road can cause fasteners to loosen over time.
•  Do not drive the vehicle in tall grass. Doing so can damage the vehicle or electronics.

CAUTION: Do not discharge a Li-Po battery below 3V per cell. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting in loss of performance and potential fire when batteries are charged.

•  Do not apply forward or reverse throttle if the vehicle is stuck. Applying throttle in this instance can damage the motor or ESC.
•  After driving the vehicle, allow the electronics to cool before driving the vehicle again. IMPORTANT: Keep wires away from all moving parts.

BEFORE RUNNING YOUR VEHICLE

1.  Check for free suspension movement. All suspension parts and steering components should move freely. Any binds will cause the vehicle to handle poorly.
2.  Check that all servo lead wires and extensions are safely secured and clear from any moving or rotating parts.
3.  Charge a battery pack. Always charge the battery pack as per the battery and/or charger manufacturers’ instructions.
4.  Perform a Control Direction Test.
5.  Drive the vehicle at a slow speed and set the steering trim on the transmitter so the vehicle drives straight with no input to the steering.

RUN TIME

The largest factor in run time is the capacity of the battery pack. A larger capacity (mAh) rating increases the amount of run time experienced.
The condition of a battery pack is also an important factor in both run time and speed. The battery connectors may become hot during driving. Batteries will lose performance and capacity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries
and electronics over time. Sudden acceleration will also lead to shorter run times.

TO IMPROVE RUN TIMES

•  Keep your vehicle clean and well maintained.
•  Provide more airflow to the ESC and motor.
•  Change the gearing to a lower ratio. A lower ratio decreases the operating temperature of the electronics. Use a smaller pinion gear to lower the gear ratio.
• Use a battery pack with a higher mAh rating.
•  Use the optimum charger to charge battery packs (Visit your local hobby dealer for more information).
•  Cycle your batteries on a charger with a mAh display to verify they are delivering the rated capacity. Replace them if they fall short.

VEHICLE MAINTENANCE

The following items require semi-frequent maintenance. Always clean screw threads and apply removeable thread locking compound when threading machine screws into metal parts.

SHOCK DISASSEMBLY/CLEANING

Remove the shocks and service as needed. Replace worn parts.

1. Pull the spring up and away from the lower cup. Slide the lower spring cup up and off of the shaft. Clean with a soft brush. Remove the shock boot.
2.  Use the wheel wrench to hold the shock body and remove the top cap. Empty the fluid from out of the shock.
3.  Hold the shaft with a multi-wrench and remove the shock end. Push the shaft into the shock body and remove through the top. Remove the lower shock cap, dust cover, O-rings and spacer. Clean the shock body. Install new O-rings, re-install the spacer, replace the O-ring and install the lower shock cap. DO NOT TIGHTEN. Install the shock shaft through the shock bottom and tighten the bottom cap. Re-install the boot and shock end on the shaft.
   

REFILLING/BLEEDING SHOCKS

1.  Fill the shock body 5mm (0.2 in) from the top with 25wt silicone shock oil
   (TLR74004 2oz, TLR74022 4oz).

2.  Slowly move the piston up and down 5 times, allowing air to rise to the top. Let the shock sit for 5 minutes.

3.  With the piston all the way down, fill the shock body 1mm (0.04 in) from the top. Replace the shock cap, spring and spring cup.

DIFFERENTIALS

Center

| Has less forward drive and can unload the drivetrain easier under acceleration, which can be good on rough and slick tracks| Has more acceleration and increases on-power steering, but decreases off-power steering. Thicker center diff oil is better on high traction/smooth tracks
Rear| Has more side traction and increased steering in the middle of a turn| Has less steering in the middle of the turn but more forward traction

FRONT DIFFERENTIAL

1.  To Remove the front differential from the axial housing, start by removing the steering servo and servo mount from the axle.
2.  Remove the screw holding the upper 4-link bars to the mount
3.  Remove the Sway bar links, shocks and lower 4-link bars from the axle housing.
