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), 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 to follow 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.

»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 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 WD-40 ^® solvent or any other 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 bearings with lightweight motor oil.

The Twin Hammers rock racer comes with a Spektrum™ DX3E Transmitter with 2.4GHz DSM ^st technology. The system will not interfere with radio systems operating on legacy frequencies, such as 27MHz or 75MHz, neither will you experience any overlapping interference from other 2.4GHz systems. The transmitter and receiver are bound together at the factory to uniquely operate together.

For more information on the transmitter, go to www.horizonhobby.com and click on the support tab for the Spektrum DX3E to download the instruction manual.

FACTORY SETTINGS OF RADIO/ESC

The Electronic Speed Control was calibrated at the factory. When you turn on and run the vehicle for the first time, you may need to slightly adjust the Throttle Trim. If the vehicle creeps forward or backwards, make a fine adjustment to the Throttle Trim knob on the transmitter. Bumps during transportation can slightly alter the default settings.

BindingG Procedure

1 Ensure the transmitter and vehicle are both turned off.
2 Insert the Bind plug (included) into the receiver slot labeled BIND.

important: You do not need to remove any other plugs to rebind.

3 Connect a fully charged battery to the EC3 "connector on the ESC.
4 With the Bind plug installed, turn on the vehicle. The receiver LED will start to blink.

5 Turn on the transmitter. The transmitter LED will start to blink.
6 After a few seconds, the receiver and transmitter LEDs will turn solid, indicating they have been bound.
7 Turn off the vehicle, then the transmitter.
8 Remove the bind plug from the receiver.
9 Turn on the transmitter and then the vehicle to ensure operation. If the transmitter does not control the vehicle, repeat steps 1–8 above. If after several attempts you are unsuccessful, please contact Horizon product support.

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. You need to 'bind' your chosen Spektrum ^™ DSM technology equipped vehicle transmitter to the receiver for proper operation. The DX3E transmitter and SR300WP receiver are pre-bound at the factory. If you need to rebind, follow those instructions.

receiVer antenna

Using your fingers, gently straighten the antenna wire to be close to vertical from the chassis for the best radio reception.

notice: Do not cut or bend the receiver antenna or damage to the receiver may result.

Control test

forWard

Brake/reVerSe

Perform a control test with the vehicle wheels off the ground. If the wheels rotate after the vehicle is powered ON, adjust the "TH. Trim" knob until they stop. To make the wheels move forward, pull the trigger. To reverse them, wait for the wheels to stop, then push the trigger. When moving forward, the wheels should maintain a straight line without any steering wheel input. If not, adjust the "ST. Trim" knob so the wheels maintain a straight line without having to turn the steering wheel.

run time

The single largest factor in run time is the mAh capacity of your battery pack. The larger the mAh rating, the more run time you will experience. For example: if you have a 4500mAh battery pack, you can expect close to twice the run time of a 2000mAh battery pack.

The condition of a battery pack is also an important factor in both run time and speed. The longer you run, the hotter the battery plugs can get. Check the standard plugs periodically. As batteries see more use, they will degrade in performance and capacity.

How you drive your Twin Hammers vehicle also affects your run times. If you are performing runs, going from a standstill to full speed repeatedly, you are taxing your batteries and electronics. Hard acceleration draws a lot of current from any battery and will lead to shortened run time.

If the bearings are dirty, they will cause significant drag, causing reduced run times and speed.

To improve run times, consider the following:

»Keep your vehicle clean and maintained.

»Allow more airflow to the heat sink of the ESC.

» Change the gearing to a lower ratio; this will make the electronics run cooler. To change gear ratio, use a smaller pinion gear or a larger spur gear than those originally supplied (the Twin Hammers vehicle comes with a 28-tooth pinion and a 78-tooth spur gear).

»Change to battery packs of higher mAh rating.

» Verify you are using the best charger for your batteries. See your local hobby dealer for a wide selection of compatible chargers.

2-SPeed tranSMiSSion

Your Twin Hammers trail racer features a 2-speed transmission, giving you the option for fast driving or rock crawling all in one vehicle. To change between speeds:

1. Press the top of the Channel 3 switch for low speed driving.

2. Press the bottom of the Channel 3 switch for high speed driving.

important: If you decide to use a transmitter other than the one included with the vehicle, limit the Channel 3 travel end points and gradually increase the travel until the vehicle shifts. Failure to limit the travel endpoints will damage the transmission servo.

tuninG, adJustinG & maintaininG your VehiCle

After you become familiar with driving your vehicle, you may need to reset or make adjustments to the alignment. Make sure to work on a flat work space. This will enable you to easily and more quickly make both Toe-in and Camber adjustments. These adjustments should be set with the vehicle sitting at its normal ride height.

»Keep your vehicle clean by using a soft brush to remove dirt and dust.

»Look for cracks in the suspension arms and other molded parts.

»Check the beadlock wheel hardware.

»Check that all the wheel bearings are clean and lubricated.

»Using your tools, attempt to tighten all the screws and nuts.

»Verify that the Camber Links and Steering Linkage are not bent.

»Check that the Toe and Camber settings are as desired and equal.

»Remove the gear cover.

• Check the Spur gear for wear.

- Check the Pinion gear.

- Check the Slipper Pads for wear.

» Take the shocks off the vehicle and check them for leakage. It may be time to rebuild them.

» Look over all the wiring and connections for bare wire or any place that could lead to a short-circuit.

»Verify the ESC is securely mounted to the chassis.

»Verify the receiver is still securely mounted to the chassis.

» Turn on the radio. If the Green LED is off or dim, replace the 4 AA batteries in the transmitter.
