RTR KITS - REQUIRED FOR OPERATION
THINGS NEEDED
Glow Fuel
20%
AA Batteries ( 12 pcs )
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 or heli fuels, they will
over heat engine.
• Buy LONG glow plugs, like OFNA/PICCO Plug (#51007). Use plugs
without idle bar. Do NOT use plugs, like the MC-59 or OS-8
In your box you will find..
• #10163 - Bottle, spout top
• #10218 - Red “C” size glow heater
You need to get batteries for the radio transmitter and the car receiver packs.
• Radio TX needs (8) eight AA batteries.
• Car needs (4) four AA Ni-cad batteries 2000Mah OFNA #10196 or (4) Alkaline.,
Alkaline type batteries will work, but braking will be reduced and 30 minute life. The
best for car, is to use a 5 cell hump receiver pack for increased voltage and longer
life..
Recommended Option:
You may want to upgrade the car battery pack to a Ni-Cad or NiHm 5 cell
type(600AE). This will give more run time. OFNA #10212 1000NiMh Hump Pack and
#10212 NiHm Hump Pack,

car near any water or wet dirt.
• Do not run on public streets. It is very easy to have the
car run over or damaged by hitting the curb.
• Do not operate car in tight confined places. The car is
very fast and will easily hit something.
• Do not run near people or animals.
and will too easily hit someone.
• Due noise, you will want to consider the surrounding
area when operating the car.
• Do not operate the car at night. You will not be able to
drive it without hitting something.
• Do not operate the car indoors. Engine exhaust is not
healthy.
Glow Fuel
• Glow fuel is poisonous!

The car is very fast
Precautions
• This kit is not a toy. Always run car with a second
person as a spotter and pitman.
• Hot Parts - The pipe, manifold, engine and head are very
hot and will cause burns.
• Rotating Parts - Keep hands away from the drive train,
wheels, and engine when engine is running.
• Radio - Check batteries life before running the car. If
radio does not have full control of the car with steering
and/or throttle/brake do not run until corrected. Failure to
correct this will result in possible injury and damage to the

• Glow fuel - Do leave the glow fuel unattended with the lid
off. Fuel contains Methanol and Nitro Methane and is
flammable and poisonous.
Store fuel in cool ventilated location. Refer the glow fuel
engine if left in tank.
• Always turn off the car BEFORE turning off radio.

Note:
Battery life is short when using Alkaline batteries. For safety, we recommend using
Alkaline batteries for only 30 minutes before testing.. Battery strength affects braking
power and radio range. If voltage drops while running the car, you will loose control and
destroy your car! This is NOT covered under warranty.
To increase run time, upgrade receiver battery to a 5-cell hump pack. But, the most
important step you can make, “is to always use fully charged or fresh batteries when
running your car”. Another choice is to use OFNA #10196 2000 mAh NiMh AA batteries in
car and radio.

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 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 w/threaded shalf...
• Force Pull Start Engines required NO spacer and no shaft cutting. The engines comes with an alum cast driver
washer, you use this part as the spacer, not the alum. washer shown. Also, use the special flywheel brass corn.
This corn fits the thread shaft diameter so you can tighten the flywheel against the drive hub.
