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
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.
• While the air filter assembly can be designed to limit or
restrict water ingestion into the engine, no air filter is completely
waterproof. If too much water is ingested into the engine, severe
damage to the engine may result.
• Do not expose your engine to rapid changes in temperature.
These engines tend to operate at temperatures between 200–250°F
(93–121°C) in normal operating conditions. If the engine is exposed
to cold water while operating at this temperature, there is a risk of
“thermal shock”, which could cause undue stress on the engine and
a shortened engine lifespan.
• Driving in wet conditions can reduce the life of the engine. 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 reduce the load on the engine (and engine temperatures)
when running in mud, deeper puddles, or any wet conditions that
will increase stress on the engine 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 WD-40
®
solvent or any other water-displacing light oil.
• 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.
• Engine air filter element.
• Engine clutch assembly, including shoes and bearings.
