You need to get batteries for the radio transmitter and the car receiver
packs.
• Radio TX needs (8) eight AAbatteries
• Car needs (4) four AA batteries.
Recommendation:
You may want to upgrade the car battery pack to a Ni-Mh 5 cell Flat
type. This will give more run time.
You will need to buy a few items to start the engine and run the car.
• Use 20% nitro CAR fuel. Do not use airplane fuels, they will over
heat engine.
• Buy long glow plugs, like OFNA/PICCO P-7 (#51007). Use plugs
without idle bar. Do NOT buy hot plugs, like the MC-59.
In your box you will find..
• #10218 - Red “C” size glow heater

Notes:
Non-Pull Start Engines...
• Alum. Washer behind the flywheel is not needed when using Force engines or similar types. O.S. Engines will
require washer spacer.
• To check!..place the brass corn #10330 (big hole) against the engine bearing, then flywheel. You should be
covering one or two thread of the engine shaft. If this is the case, you do not need an additional washer behind the
flywheel.
You must cut the engine shaft if too long. Count 6 threads in front of the flywheel and mark. This is all you need to
tighten the clutch nut and mount the flywheel.
Force Pull Start Engine...
• Force Pull Start Engines required NO additional spacer and no shaft cutting. The Force engines comes with an
alum. cast driver washer, you use this part as the spacer, not the alum. washer shown for O.S. installs
But, you must find the #10329 brass corn (sml hole) for Flywheel. This special corn fits the smaller thread
diameter of the engine shaft. It will center the flywheel when tightening the clutch nut.
*Tighten the strap
and cut off the excess.

Close master needle by turning clockwise until it stops.
Then open needle by turning counterclockwise 3 turns
(rich setting). When running car, adjust carb with 1/8 clockwise turns,
slowly leaner, until the top speed good. Check engine
temp, if possible, for no more 250 degrees.
Adjust barrel stop so it will not close, accept for a small gap.
This gap will be the idle setting. You will notice the idle will
increase with a wide gap.
Adjust low end needle for best throttle response. Use only
small turns. From idle, give it full throttle, if throttle is slow
lean out needle until good.
