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 certifi ed 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, fi ngers, 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.
