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.
• Adjust the Toe and Camber settings, if necessary.
• 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 and receiver are secure on the chassis. Replace the double-sided tape,
if necessary.
• 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 at 877 504 0233. 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 at 877 504 0233.
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.
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 3–5 hours of use, depending
on the driving conditions.
• Remove the shock from the vehicle.
• Remove the bottom cartridge 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 bottom cartridge.
• 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.
