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. While the various electronic
components used in the vehicle may be waterproof, 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 200–265°F (93–129°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.
As the user of this product, you are solely responsible for operating it in a manner that
does not endanger yourself and others or result in damage to the product or property
of others.
This model is controlled by a radio signal subject to interference from many sources
outside your control. This interference may cause momentary loss of control, so it is
advisable to always keep some distance in all directions around your model as this
margin will help you avoid collisions or injury.
• Always ensure all screws and nuts are tightened.
• Always carefully follow the directions and warnings for this and any optional
support equipment.
• Always keep all chemicals, small parts and anything electrical out of the reach
of children.
• Always ensure the failsafe is properly set during binding.
• Always operate your model in an open area away from cars, traffic and people.
• When operating this vehicle, always keep it at least 20 feet from spectators,
especially small children.
• Never run your vehicle through deep water that will submerge the vehicle.
• Never run your model in a public street where damage can occur.
• Never run your model with low transmitter batteries.
• When finished operating, always power off the engine first, then the receiver,
then the transmitter.
• Always perform maintenance on the vehicle after each and every use. Due to
engine vibration, all screws and nuts will need to be checked to ensure they
are tight.
