THE INSTRUCTIONS THAT CAME WITH THEM.
YOU NEED TO CHARGE YOUR CAR BATTERY, INSTALL BATTERIES IN YOUR TRANSMITTER, AND SET UP
YOUR RADIO CONTROLS ACCORDING TO THE MANUFACTURERS’ INSTRUCTIONS . CAREFULLY CHECK ALL
FUNCTIONS FOR STEERING AND MOTOR CONTROL BEFORE YOU TAKE THE CAR OUT. WHEN YOU TAKE THE
CAR OUT, SET IT DOWN AND ADJUST THE DIFF SO THAT IT SLIPS A LITTLE WHEN YOU TAKE OFF HARD SO
THAT THE CAR WON’T SPIN OUT EASILY, ESPECIALLY IF YOU’RE RUNNING ON A DIRTY PARKING LOT. RUN
THE CAR SLOWLY AT FIRST AND BUILD UP SPEED AS YOU GET USED TO IT . MAKE ADJUSTMENTS AS
NEEDED. OF COURSE DON’T FORGET, THIS CAR IS MADE FOR LEFT TURN OVAL RACING, AND WILL NOT
HANDLE WELL IF YOU TRY TO MAKE RIGHT TURNS WITH IT.
YOU CAN USE WD-40 TO CLEAN YOUR TIRES AND SOFTEN THEM FOR BETTER TRACTION ON SOME SUR-
FACES. YOU CAN USE A PIECE OF SCRAP LEXAN BODY MATERIAL TO ADD TO THE HEIGHT OF THE REAR
SPOILER FOR MORE REAR TRACTION IN HIGHER SPEED TURNS.
YOU CAN ADJUST THE ANGLE OF THE FRONT A-ARMS TO GET EVEN TIRE WEAR BY TIGHTENING THE LOCK
NUTS AS NEEDED. YOU SHOULD HAVE THE ARMS LEANED BACK A LITTLE TO IMPROVE THE STEERING AND
WEAR THE TIRES MORE EVENLY. LOOK AT THE TIRE WEAR AFTER RUNNING THE CAR AND ADJUST AS
NECESSARY.
THIS CAR IS MADE FROM QUALITY MATERIALS AND WILL TAKE A LOT OF ABUSE , BUT CAN BE BROKEN IF
RUN INTO SOLID OBJECTS REPEATEDLY AT HIGHER SPEEDS. REPLACEMENT PARTS ARE AVAILABLE
THROUGH YOUR LOCAL HOBBY SHOP. THE DIFF, BUSHINGS, MOTOR, AND THE STEERING PARTS WILL
WORK BETTER IF KEPT CLEAN AND LUBRICATED.ABOVE ALL, GO OUT THERE AND HAVE SOME FUN WITH
