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.
