 RTR KITS - REQUIRED FOR OPERATION
THINGS NEEDED 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
Glow Fuel
20%

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
AA Batteries ( 12 pcs ) 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 10214

Note:
Battery life is short when using Alkaline batteries. For safety, we recommend using Full Throttle
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.
