Your new Horizon Hobby vehicle has been designed and built with a combination of 

waterproof and water-resistant components to allow you to operate the product in many 

“wet conditions,” including puddles, creeks, wet grass, snow and even rain.
While the entire vehicle is highly water-resistant, it is not completely waterproof and your vehicle 

should NOT be treated like a submarine. The various electronic components used in the vehicle, 

such as the Electronic Speed Control (ESC), servo(s) and receiver are waterproof, however, most 

of the mechanical components are water-resistant and should not be submerged.
Metal parts, including the bearings, hinge pins, screws and nuts, as well as the contacts in the 

electrical cables, will be susceptible to corrosion if additional maintenance is not performed 

after running in wet conditions. To maximize the long-term performance of your vehicle and 

to keep the warranty intact, the procedures described in the “Wet Conditions Maintenance” 

section below must be performed regularly if you choose to run in wet conditions. If you are 

not willing to perform the additional care and maintenance required, then you should not 

operate the vehicle in those conditions.

CAUTION:

 Failure to exercise caution while using this product and complying with the 

following precautions could result in product malfunction and/or void the warranty.

GENERAL PRECAUTIONS

• Read through the wet conditions maintenance procedures and make sure that you have all 

the tools you will need to properly maintain your vehicle.

• Not all batteries can be used in wet conditions. Consult the battery manufacturer before 

use. Caution should be taken when using Li-Po batteries in wet conditions.

• Most transmitters are not water-resistant. Consult your transmitter’s manual or the 

manufacturer before operation.

• Never operate your transmitter or vehicle where lightning may be present.
• Do not operate your vehicle where it could come in contact with salt water (ocean water or 

water on salt-covered roads), contaminated or polluted water. Salt water is very conductive 

and highly corrosive, so use caution.

• Even minimal water contact can reduce the life of your motor if it has not been certified as 

water-resistant or waterproof. If the motor becomes excessively wet, apply very light throttle 

until the water is mostly removed from the motor. Running a wet motor at high speeds may 

rapidly damage the motor.

• Driving in wet conditions can reduce the life of the motor. The additional resistance of 

operating in water causes excess strain. Alter the gear ratio by using a smaller pinion or larger 

spur gear. This will increase torque (and motor life) when running in mud, deeper puddles, or 

any wet conditions that will increase the load on the motor for an extended period of time.

WET CONDITIONS MAINTENANCE

• Drain any water that has collected in the tires by spinning them at high speed. With the 

body removed, place the vehicle upside down and pull full throttle for a few short bursts 

until the water has been removed.

CAUTION:

 Always keep hands, fingers, tools and any loose or hanging objects 

away from rotating parts when performing the above drying technique.

• Remove the battery pack(s) and dry the contacts. If you have an air compressor or a can of 

compressed air, blow out any water that may be inside the recessed connector housing.

• Remove the tires/wheels from the vehicle and gently rinse the mud and dirt off with a 

garden hose. Avoid rinsing the bearings and transmission.

NOTICE:

 Never use a pressure washer to clean your vehicle.

• Use an air compressor or a can of compressed air to dry the vehicle and help remove any 

water that may have gotten into small crevices or corners.

• Spray the bearings, drive train, fasteners and other metal parts with a water-displacing light 

oil. Do not spray the motor.

• Let the vehicle air dry before you store it. Water (and oil) may continue to drip for a few hours.
• Increase the frequency of disassembly, inspection and lubrication of the following:  

 - Front and rear axle hub assembly bearings.
 - All transmission cases, gears and differentials.
 - Motor—clean with an aerosol motor cleaner and re-oil the bushings with lightweight 

motor oil.

WATER-RESISTANT VEHICLE WITH WATERPROOF ELECTRONICS

QUICK START

Please read the entire manual to gain a full understanding of the LMT Solid Axle Monster Truck RTR vehicle, fine-tuning the setup and performing maintenance.

1. Read the safety precautions found in this manual.
2. Charge a battery for the vehicle. Refer to the included charging warnings and 

instructions for battery charging information.

3. Install the AA batteries in the transmitter. Only use alkaline  

or rechargeable batteries.

4. Install the fully charged battery in the vehicle.

5. Power ON the transmitter and then the vehicle. Wait 5 seconds for the ESC to 

initialize. Always power the transmitter ON before the vehicle and power it OFF 

after the vehicle has been powered OFF.

6. Check the steering and throttle control directions. Verify that the servos are 

moving in the correct direction.

7. Drive your vehicle.
8. Perform any necessary maintenance.

CHARGING THE BATTERY

The LMT Solid Axle Monster Truck requires a requires a 2S or 3S hardcase LiPo Battery with IC5 

plug (not included). The included Spektrum

 Firma

 SMART 130A Brushless ESC (SPMXSE1130) 

has an IC5

 battery connector. We recommend a Spektrum 5000mAh 2S 7.4V 50C SMART 

LiPo Battery (SPMX50002S50H5), or a Spektrum 5000mAh 3S 11.1V 50C SMART LiPo Battery 

(SPMX50003S50H5).

We recommend charging Spektrum SMART Batteries paired with Spektrum Smart Chargers 

because Smart chargers will automatically configure the charge settings for Smart batteries. We 

We recommend the Spektrum S1100 SMART AC Charger, 1x100w (SPMXC1080) with IC3 to 

IC5 charge adapter (SPMXCA507).

Refer to your battery and charger manuals for usage, safety, and charging information.

SPEKTRUM SMART TECHNOLOGY

The LMT Solid Axle Monster Truck includes Spektrum Smart Technology in the ESC and 

receiver, which can provide you with telemetry information like battery voltage from your 

vehicle. The included DX3 Smart transmitter features an LED display to show the battery level 

of your vehicle during operation.

For additional Smart functionality, consider upgrading to a more advanced Smart Technology 

compatible Spektrum transmitter like the DX5C (SPMR5100- transmitter only), or DX5 Pro 

(SPMR5010- transmitter only). Use Spektrum Smart batteries to power your LMT Solid Axle 

Monster Truck to take full advantage of Smart Technology, which can communicate detailed 

battery data through the system as well.
