SAFETY PRECAUTIONS AND WARNINGS

As the user of this product, you are solely responsible for operating 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 can cause momentary loss of control, so it is advisable to always keep a safe distance in all directions around your model as this margin will help avoid  collisions or injury.

  • Never operate your model with low transmitter batteries.

  • Always operate your model in open spaces away from full-size vehicles, traffic and people.

  • Never operate the model in the street or in populated areas for any reason.

  • Carefully follow the directions and warnings for this and any optional support equipment (chargers, rechargeable battery packs, etc.) you use.

  • Keep all chemicals, small parts and anything electrical out of the reach of children.

  • Never lick or place any portion of the model in your mouth as it could cause serious injury or even death.

  • Exercise caution when using tools and sharp instruments.

  • Take care during maintenance as some parts may have sharp edges.

  • Immediately after using your model, do NOT touch equipment such as the motor, electronic speed control and battery, because they generate high temperatures.
    You may burn yourself seriously by touching them.

  • Do not put fingers or any objects inside rotating and moving parts, as this may cause damage or serious injury.

  • Always turn on your transmitter before you turn on the car. Always turn off the car before turning your transmitter off.

  • Keep the wheels of the model off the ground when checking the operation of the radio equipment.

WARNING AGAINST COUNTERFEIT PRODUCTS : Always purchase from a Horizon Hobby, LLC authorized dealer to ensure authentic high-quality Spektrum product. Horizon Hobby, LLC disclaims all support and warranty with regards, but not limited to, compatibility and performance of counterfeit products or products claiming compatibility with DSM or Spektrum technology.

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 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. Consultthe battery manufacturer before use. Caution should betaken when using Li-Po batteries in wet conditions.

  • Most transmitters are not water-resistant. Consultyour transmitter’s manual or the manufacturer beforeoperation.

  • 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 saltcovered 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 bearings with lightweight motor oil.

  • Drain any water that has collected in the tires by spinning them at high speed. With the body removed, place the vehicle upside down and pull full throttle for a few short
    bursts until the water has been removed.

Connect batteries, turn on TX and press/hold the set button ‘A’. Turn the switch on ‘B’ and release the set button when the RED light flashes on the ESC.

ARRMA SLT3 3 Channel Transmitter-fig11

Battery Modes
If using LiPo batteries you must set the correct battery mode on the ESC (electronic speed controller) to prevent battery damage.
Temperature Protection
If the ESC temperature exceeds 105 degrees Celsius/221 degrees Fahrenheit, the ESC will enter temperature protection mode and the green status LED will blink. Once the ESC has cooled down it will resume normal operation after it has been turned off and back on again.
ESC Tuning Options
The ARRMA BLX brushless ESC is setup for use straight from the factory, if you want to alter the settings for your track or driving style please see the table and steps below:

To alter ESC settings

  1. Connect a battery. Press and hold the set button and turn on ESC. The RED LED will flash.
