Removing The Front Differential
To remove the front differential, the “front clip” of your 8IGHT RTR has to be removed. Remove four 8-32 flathead screws from
the chassis (fig. 1). Remove the forward most two silver 5-40 button head screws from the front chassis brace. Pop the
steering tie rod ends off of the right and left steering spindles. Remove the bumper and the spacer from under the front
chassis brace. Lift the front clip up then forward to remove it from the chassis. (fig. 2)

Radio Operation
It is important that you familiarize yourself with the radio system, as this is your direct link to the buggy.
Never run your buggy with low receiver or transmitter batteries.
Never leave the power on or the batteries will not last long.
Always turn the transmitter ON
before
turning the buggy ON.
When finished running, always turn the buggy OFF
before
the transmitter.
For best operation it will be necessary to keep the "trims" adjusted for both the steering and throttle as noted below.
Steering Trim:
The buggy should go straight without turning the steering wheel. If not, tap the trim lever found just
above the steering wheel in the direction needed for the buggy to go straight. Each tap of the trim button will be accom-
panied by an audible tone indicating a change has been made. It may take several taps to get the correct trim setting.
Throttle Trim:
The buggy should idle without the tires rotating when the trigger is at its neutral position. If not, tap the
trim tab located to the right of the steering wheel to reposition the throttle servo and close the carburetor and apply
more brakes. Note that additional braking force is applied when you push the trigger forward.
Maintenance
In addition to the service needs pointed out in this guide, you should try to maintain your new buggy for proper
performance and to prevent wear. If dirt gets in the moving parts it can seriously hinder the performance of the model.
Use compressed air, a soft paintbrush, and/or toothbrush to remove dirt and dust. Avoid using solvents, if possible, as
this can actually wash the dirt into bearings and areas not accessible without disassembly causing additional wear. We
suggest you follow these basic guidelines.
Remove as much freestanding dirt and dust as noted above.
Never leave fuel in the tank for more than a couple of hours.
When done running for the day or longer, let the engine run out of fuel. Remove the air cleaner and pour a little
WD40, or quality after-run engine oil into the carburetor and spin the engine over a few seconds.
If needed, clean and re-oil the air cleaner before installing it back on the truck.
Inspect the buggy for worn, broken, or binding parts and repair as necessary.
Servicing the Differentials
Your 8ight RTR has three differentials and they should be serviced periodically. Be sure to clean and inspect all of
the gears and replace if severely worn. Always use plenty of high-quality grease (like Teal Losi3066) on all gears.
NOTE: The differentials can also be made into racing type viscous diffs as noted on page 7. Always service one diff
a time and pay close attention to install the housing so the key in the housing matches up with the cutout in the
chassis.
