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 al-
low 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 run-
ning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 mainte-
nance 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:

• Alltransmissioncases,gearsanddifferentials.
