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 longterm 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 verify you have all the tools you need to properly maintain the 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 the 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

4

LOSI® MICRO-B 1/24 2WD BUGGY RTR

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 · 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.
CAUTION: Always keep hands, fingers, tools and any loose or hanging objects away from rotating parts when performing the above drying technique.
· Remove the battery pack(s) and dry the contacts. If you have an air compressor or a can of

EN
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. 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 bushings with lightweight motor oil.

BINDING

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. The transmitter and ESC/receiver are bound at the factory. If you need to rebind, follow the instructions below:
1. Connect a fully charged battery to the ESC/ receiver.
2. Power ON the ESC/receiver, holding the button for 3 seconds until the red light flashes quickly.
3. Power ON the transmitter. The ESC/receiver’s red LED will turn solid when the bind is successful.
4. Power OFF the ESC/receiver to save the settings.
5. Power OFF the transmitter. You must rebind when binding the receiver to a different transmitter.
NOTICE: Do not attempt to bind the transmitter and receiver if there are other compatible transmitters in bind mode within 400 feet. Doing so may result in unexpected binding.

DRIVING PRECAUTIONS

· Maintain sight of the vehicle at all times. · Routinely inspect the vehicle for loose wheel
hardware. · Routinely inspect the steering assembly for any
loose hardware. Driving the vehicle off-road can cause fasteners to loosen over time. · Do not drive the vehicle in tall grass. Doing so can damage the vehicle or electronics. · Stop driving the vehicle when you notice a lack of power. Driving the vehicle when the battery is discharged can cause the receiver to power off. If the receiver loses power, you will lose control of the vehicle. Damage due to an overdischarged Li-Po battery is not covered under warranty.

CAUTION: Do not discharge a Li-Po battery below 3V per cell. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting in loss of performance and potential fire when batteries are charged.
· Do not apply forward or reverse throttle if the vehicle is stuck. Applying throttle in this instance can damage the motor or ESC.
· After driving the vehicle, allow the electronics to cool before driving the vehicle again.
IMPORTANT: Keep wires away from all moving parts.

PERFORMING A CONTROL DIRECTION TEST

Perform a control test with the vehicle wheels off the ground. If the wheels rotate after the vehicle is powered ON, adjust the ST 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 largest factor in run time is the capacity of the battery pack. A larger mAh rating increases the run time.
The condition of a battery pack is also an important factor in both run time and speed. The battery connectors may become hot during driving. Batteries will lose performance and capacity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries and electronics over time. Sudden acceleration will also lead to shorter run times.

TO IMPROVE RUN TIMES · Keep your vehicle clean and well maintained. · Allow more airflow to the ESC and motor. · Change the gearing to a lower ratio. A lower ratio decreases the operating temperature of the electronics. Use a smaller pinion gear or larger spur gear to lower the gear ratio. · Use a battery pack with a higher mAh rating. · Use the optimum charger to charge battery packs. Visit your local hobby dealer for more information.

POWERING OFF THE VEHICLE

1. Power OFF the ESC. 2. Power OFF the transmitter. 3. Remove and charge the batteries.
IMPORTANT: Keep wires away from all moving parts. After driving the vehicle, allow the electronics to cool before driving the vehicle again.

TUNING, ADJUSTING AND MAINTAINING THE VEHICLE

· Examine your vehicle on a regular basis. · Use a brush to remove dirt and dust. · Look for damage to the suspension arms and
other molded parts. · Re-glue the tires to the wheels, if necessary. · Use suitable tools to tighten fasteners. · Make sure the camber and steering linkages
are not bent. Replace any bent linkages. · Remove the shocks and inspect them for
damage. Rebuild the shocks if oil is leaking. · Inspect electronics and batteries for exposed
wires. Repair exposed wires with shrink-wrap or replace the wire. · Make sure the ESC / receiver are secure on the chassis. · Power on your transmitter. If the light is flashing, replace the batteries in the transmitter. · Check the spur gear for wear.

SERVICE/REPAIR
RADIO/SPEED CONTROL AND MOTOR If any problems other than those covered in the troubleshooting section arise, please call the appropriate electronics service department. They will be able to give the problem additional specific attention and provide instructions for the solution.
MAINTENANCE If any questions other than those covered in the troubleshooting or maintenance sections arise, please call the appropriate Horizon product support department.
CLEANING Performance can be hindered if dirt gets in any of the moving suspension parts. Use compressed air, a soft paintbrush, or a toothbrush to remove dust or dirt. Avoid using solvents or chemicals as they can actually wash dirt into the bearings or moving parts, as well as cause damage to the electronics.

10

LOSI® MICRO-B 1/24 2WD BUGGY RTR

SHOCK CLEANING
Oil-filled shocks will require regular maintenance due to the oil breaking down or getting dirty. This maintenance should be performed after about every 35 hours of use, depending on the driving conditions.
· Remove the shock from the vehicle. · Remove the shock cap from the shock body
and dispose of fluid. · Disassemble the shock. Clean thoroughly
with a plastic- and electronic-safe degreaser (DYNE50001). Dry parts before assembly. · Re-assemble the shock and refill the shock body with silicone fluid (22.5 weight recommended, TLR74003). · Slowly move the shaft and piston up and down to remove air bubbles. · Move the piston to the midway point of the body and install the shock cap. · Wipe off any overflowing fluid. · Re- install the shock on the vehicle.
RIDE HEIGHT ADJUSTMENT
Ride height is an adjustment that affects the way the vehicle jumps, turns and goes over bumps. Drop one end of the vehicle from approximately 6 inches (152 mm) in height onto a flat surface. When dropping the front of the vehicle, after the vehicle settles, make sure the front arms are equal and parallel to the flat surface. Do the same with the rear to make sure both arms are parallel with the flat surface.
Lowering the front ride height increases steering, but decreases traction. Lowering the rear ride height increases traction, but decreases steering.
