SOCKET OR WRENCH, AND A 7/16 SOCKET FOR THE BODY POSTS AND DIFF NUT. HEX WRENCHES TO FIT
THE SOCKET HEAD SCREWS ARE PROVIDED. THERE ARE ALTERNATE POSITIONS FOR THE MOTOR AND
BATTERY PACK SO YOU CAN DISTRIBUTE THE WEIGHT AS YOU WISH. THERE IS PLENTY OF ROOM ON THE
CHASSIS TO MOUNT THE RECEIVER, ESC AND STEERING SERVO IN VARIOUS LOCATIONS. OUR PICTURES
SHOW ONE OF MANY SETUPS THAT YOU CAN USE TO CUSTOMIZE YOUR CAR TO SUIT YOUR END USE. WE
PROVIDE AN ANTENNA TUBE AND MOUNTING IF YOU ARE USING A RADIO THAT NEEDS ONE.
THIS KIT REQUIRES A 540 OR 550 SIZE MOTOR, BATTERY PACK, 2 CHANNEL RADIO SYSTEM WITH 1
SERVO AND ESC (MAKE SURE THE ESC WILL WORK WITH THE MOTOR YOU CHOOSE) AND A SERVO
SAVER TO FIT THE SERVO YOU HAVE CHOSEN. YOU WILL ALSO NEED PAINT FOR THE LEXAN BODY.

6 -5245 CHASSIS SPACERS TO ONE OF THE 5070
CHASSIS SIDES. USE 3/8” LONG CAP SCREWS ON
ALL BUT THE CENTER ONE NEAR THE TOP OF THE

SERVO TRAY, 5242 BATTERY TRAY, AND 5071 BODY
MOUNT INTO THE CHASSIS SIDE. MAKE SURE THEY
FIT ALL THE WAY INTO THE SLOTS. IF ANY ARE TOO
TIGHT, USE A SMALL FILE OR SANDPAPER ON THE
TABS THAT GO IN THE SLOTS.

THE SAME MANNER AS YOU USED EARLIER .

ONE 7206 PLAIN NUT (THIN ONES) ON EACH 5377
KINGPIN ( THE PLAIN ONES WITH THE LONGER
THREADS). INSERT THEM THROUGH THE ENDS OF
THE FRONT AXLE PLATE AND RETAIN WITH A 7207
LOCKNUT ON EACH ONE.

STEERING BLOCK AS SHOWN AND SNAP A 5221 E-
CLIP TO RETAIN IT. SLIDE EACH STEERING BLOCK

STEP 11 SLIDE A THIN NYLON WASHER ON THE 5730
AXLE, SLIDE IT THROUGH THE BUSHINGS, ADD THE
1/4” WIDE SPACER AND THE SETSCREW HUB. IN-
STALL THE TWO SETSCREWS IN THE HUB AND
TIGHTEN EACH A LITTLE AT A TIME UNTIL THEY
CONTACT THE AXLE. FOR BEST RESULTS, REMOVE
THE HUB AND FILE FLAT SPOTS ON THE AXLE
WHERE THE SET SCREWS CONTACT IT OR USE A
DRILL TO MAKE A DIMPLE ON THE SPOT, THEN RE-
INSTALL THE HUB. THIS WILL KEEP THE HUBS FROM
SLIPPING ON THE AXLE WITHOUT HAVING TO
TIGHTEN THEM SO MUCH.
STEP 12 SNAP A DIFF
BALL IN EVERY OTHER
HOLE IN THE OUTER ROW
OF HOLES IN THE DIFF
GEAR. LUBE THEM WITH A

TIGHTEN THE NUT CAREFULLY, MAKING SURE THAT
THE DRIVE RINGS ARE IN PLACE. CHECK THE TIGHT-
NESS BY HOLDING BOTH HUBS AND TURNING THE
GEAR WITH YOUR THUMB. IT SHOULD NOT SLIP TOO
EASILY. YOU CAN DO YOUR FINAL ADJUSTMENT
WHEN YOU RUN THE CAR.
STEP 14 INSTALL THE MOTOR YOU HAVE PUR-
CHASED WITH M3 SCREWS AND WASHERS FROM
BAG C1B. YOU CAN MOUNT IT IN FRONT OR BEHIND
THE REAR AXLE TO GET THE DESIRED WEIGHT
DISTRIBUTION. INSTALL THE GEAR WITH THE SET-
SCREW AND MAKE SURE IT LINES UP WITH THE
DIFF GEAR. SLIDE THE MOTOR BACK UNTIL YOU
HAVE A VERY SMALL AMOUNT OF PLAY BETWEEN
THE GEARS. TIGHTEN THE MOTOR SCREWS , TURN
THE AXLE A COUPLE OF TIMES, CHECK THE GEAR
MESH , AND READJUST IF NECESSARY.

FOAM TAPE PROVIDED. WE SHOW IT UNDER THE
SERVO TRAY, BUT YOU CAN MOUNT IT ON TOP OF
THE TRAY OR ON THE FRONT AXLE PLATE WITH THE
OUTPUT TO THE REAR IF YOU WANT TO LEAVE
MORE ROOM TO MOVE YOUR BATTERY PACK FOR-
WARD TO INCREASE THE WEIGHT ON THE FRONT
END OF THE CAR. IF YOU MOUNT IT ON THE FRONT
AXLE PLATE, YOU MAY HAVE TO PUT BENDS IN THE
LINKAGE WIRES TO GET CLEARANCE THROUGH THE
CHASSIS SIDES. INSTALL THE LINK RODS FROM BAG
2B AND ATTACH TOGETHER WITH THE TWO COL-
LARS AND SET SCREWS. MAKE SURE THE AXLES
ARE POINTED STRAIGHT OUT. YOU CAN RECHECK
THE ALIGNMENT AFTER YOU INSTALL THE FRONT

STEP 16 IF YOU ARE USING A NICAD OR NIMH STICK
BATTERY PACK, YOU CAN MOUNT IT ACROSS THE
CHASSIS IN FRONT OF THE MOTOR AND USE THE O-
RINGS PROVIDED TO HOLD IT IN PLACE. IF YOU ARE
GOING TO RUN OVAL, YOU CAN ATTACH A PIECE OF
SCRAP PLASTIC ON TOP OF THE BATTERY PACK TO
KEEP IT FROM SLIDING SIDEWAYS IN AN ACCIDENT
OR TO KEEP IT OFFSET TO THE INSIDE.
IF YOU ARE USING A LIPO PACK YOU CAN MOUNT IT
BETWEEN THE FRAME SIDES AS FAR FORWARD OR
BACK AS REQUIRED TO GET THE WEIGHT DISTRIBU-
TION DESIRED FOR THE TYPE OF RACING YOU
WANT.

TENNA WIRE, YOU CAN ATTACH THE ANTENNA TUBE WITH TWO SMALL
TIE WRAPS SUPPLIED RIGHT BEHIND THE FRONT AXLE PLATE EITHER
OUTSIDE OR INSIDE THE CHASSIS SIDE AND RUN YOUR ANTENNA WIRE
UP THROUGH IT.
YOU CAN MOUNT YOUR RADIO RE-
CEIVER AND ESC ANYWHERE THAT IS
CONVENIENT TO GET THE WEIGHT DIS-
TRIBUTION AS DESIRED. DON’T FORGET
TO TAPE OR TIE WRAP THE WIRING SO
THAT IT WON’T DRAG ON THE TRACK OR
ROAD SURFACE. MAKE SURE TO
CHARGE YOU BATTERY PACK, MAKE
SURE EVERYTHING IS PLUGGED IN COR-
RECTLY AND ADJUST THE CONTROLS
ACCORDING TO THE RADIO MANUFAC-
TURER’S INSTRUCTIONS.
PRESS THE 5457 BUSHINGS FROM
BAG C1B INTO THE FRONT
WHEELS . OIL THE FRONT AXLES,
SLIDE THE WHEELS ON AND RE-
TAIN WITH LOCKNUTS. TIGHTEN
THE NUTS UNTIL THE SIDEPLAY IS
MINIMUM AND THE TIRE TURNS
FREELY. ATTACH THE REAR TIRES
WITH TWO 1/2” SCREWS EACH
FROM THE L2 DIFF BAG.
SET THE BODY DOWN OVER THE
CHASSIS AND MARK THE LOCA-
TIONS FOR THE BODY POST HOLES
AND REAR WHEEL WELLS.
MASK THE BODY AS YOU WISH, PAINT IT WITH PAINT MADE FOR LEXAN PLASTIC, ALLOW THE PAINT TO DRY
COMPLETELY, TRIM IT OUT , AND DRILL THE HOLES FOR THE BODY POSTS. SET THE BODY DOWN OVER
THE POSTS AND ADJUST THE NUTS TO SET THE BODY HEIGHT SO THAT IT WON’T DRAG THE TRACK.
