WATER-RESISTANT VEHICLE WITH WATERPROOF ELECTRONICS
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) and servo(s) 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. Do not use Li-Po
batteries in wet conditions.
• The included transmitter is not waterproof or water-
resistant. If using a different transmitter than the one
included, 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
• 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 or lubricant. 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.
