MUST READ THIS BEFORE RUNNING
Running a nitro kit is fun and easy, but to make this a safe and good experience you must observe a few rules. This kit is extremely fast, easily over 40MPH, and can seriously injure someone if you are not careful.
Where to run car?
• Any running area you choose must be dry. Do not run 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. The car is very fast 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!
• Glow fuel is flammable!
• Do not leave in fuel bottle with lid off at any time.
• Do not use any fuel other than glow fuel in this engine.
First Time Starting the Engine
Caution! When starting engine make sure the following is observed.
• Set engine Master needle to 3 turns (rich setting)
• Do not do this alone, get an experienced friend to help at first.
• Fill fuel tank, try not to spill fuel. Do not spill fuel on receiver
• Hold car off the ground, so it will not runaway when first starts
• Turn on Radio and check the linkage before starting engine.
• Turn on car receiver battery switch.
• Always have an air filter on the carburetor to keep dirt out.
Engine Break-in
• See Engine Page.
Emergency Stopping Engine When Running
• Remove air filter and cover carb. intake.
• Squeeze fuel line and hold until engine stops.
• With a rag, cover exhaust outlet.
Storing Car After Running
• Remove fuel from tank and fuel lines
• Turn off radio in car
• Put a few drops of after run in engine to keep it from rusting.
• Clean oil and dirt from chassis with a degreaser.
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 car or property.
• 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 label for additional precautions.
• Car Fuel tank - Never store fuel in car tank, it will ruin the engine if left in tank.
• Always turn off the car BEFORE turning off radio.
• DAMAGE DUE CAR RUN AWAY IS NOT A WARRANTY
ISSUE.
IF YOU DO NOT BREAK-IN ENGINE
CORRECTLY, MAINLY AT LOW RPM,
YOU WILL BREAK THE CONNECTING
ROD!
FAILURE TO NOT READ AND
FOLLOW BREAK-IN ENGINE
INSTRUCTIONS WILL VOID
WARRANTY!
FORCE PULL START ENGINES
Thank you for purchasing an OFNA engine. We appreciate your choice and know you will enjoy running it. Please note that the Force information in engine box is subject to change with out notice.
Carburetor Low end and barrel stop screws are pre-set by factory.... Do not change until break-in is done.
NEW ENGINE BREAK-IN
Your OFNA engine is extremely tight when the piston is at the top of the stroke and turning the crankshaft by hand.
This is normal for a new ABC type engine. The piston and sleeve are matched for fit and the top of the sleeve is tapered for a tight fit. As you run your engine, this tightness should diminish. There is no cause for alarm, because as the engine warms up, the brass sleeve will expand faster than the aluminum piston and the engine will turn freer.
As with any new engine, there are many high spots and tight fits in the matching process. High spots create hot spots that must be broke-in. Therefore, the break-in process is very important to provide good service by the OFNA engine. So, you must run the engine rich (COOL) for the first three tanks of fuel. We recommend using one gallon of 20% BLUE THUNDER 0R BYRON’S 2000 as break-in fuel. Other break-in type fuels or added oil is NOT needed. DO NOT OVER REV THE ENGINE WHEN FIRST STARTING, this could break the piston and over heat sleeve. Let engine run at low RPM for one tank to break-in connecting rod bearing before starting full break-in.
Break-in the engine in the car, by running the engine at a rich setting. Run the car from a slow to fast speed with short bursts of speed. You need to buildup a little heat in the engine, but not too hot. In a rich setting, the engine will run cold. In the leaner setting the engine run hot, this is not good yet. Do not heat up the engine too much at this time. After about one (1) tank, turn the Master Needle Valve, clock wise, 1/8 of a turn leaner or clockwise.
Keeping the fuel tank full, continue the process until you slowly turn the Master Needle Valve, 1/8 of turn each time, too a leaner point and in which the engine runs at high RPM and power, but still keep max temp. of 250 deg. F. At this point you must stop, too lean of a setting will heat up engine and damage the piston. A normal operating temperature is around 220 to 270 Deg. Temperatures of 300 Deg. and above will damage engine and shorten life.
NEEDLE SETTINGS
Master Needle Valve - main control for fuel mixture. Set at 3 to 31/2 turns from closed. Adjust this needle for maximum RPM and power without being too lean or too hot. Make sure you start at bottom of needle seat!!
Side Carburetor Needle (Low Speed) - This needle is in the center side of the carburetor and provide throttle response. It is not the idle adjustment. Set FLUSH with the brass sleeve. Turning in is Lean and Out is Rich. Do not adjust this needle until the Master Needle is set for power and top speed. This will only effect throttle response.
FOR THREE NEEDLE CARBURETORS, DO NOT ADJUST MID RANGE NEEDLE, PRESET BY FACTORY
Barrel Stop Screws - Used for adjusting Idle. Set for 1/16th inch gap to start new engines. You can open more for faster idle.
USE LONG GLOW PLUG WITHOUT IDLE BAR,
OFNA/PICCO #51007 & 51008 IS RECOMMENDED

THINGS NEEDED
RTR KITS - REQUIRED FOR OPERATION
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 or 51008).
Use plugs without idle bar. Do NOT use plugs, like the MC-59 or OS-8
In your box you will find..
• #10162- Bottle, 250cc
• #10219 - Red “D” size glow heater

You need to get batteries for the radio transmitter and the car receiver packs.
• Radio TX needs (8) eight AA batteries.
• Shaft Starter requires a 7.2Volt battery pack and charger OFNA #10195
• Car needs (4) four AA Ni-cad batteries 2000Mah or higher 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 1400NiMh Hump Pack and NiHm Battery Charger #10214

ASSEMBLY OF THE CLUTCH INTO ENGINE
• Alum. Washer behind the flywheel is not needed when using Force engines or similar types. O.S. Engines will require washer space #10048 or #10049 shim kit. This requirement old and may not be needed for current engine
#30481

production. 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.
Engine Mount
• 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 .21 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

OPTIONAL OFNA MICRO FAIL SAFE UNIT - #91002 (MICRO)
The OFNA Fail Safe unit is used to protect your RC car from loss of control due to:
• Weak radio signal
• Low radio batteries
• Radio interference of any kind
• Another radio on the same channel
• Low receiver car battery
• Fits most if not all U.S. RC radio’s
The Fuzzy logic CPU operates on 3.8 to 6.0 volts DC from your receiver battery pack.
Warning - If receiver battery is dead or removed or car battery switch is off, the fail safe unit will not function nor provide any RC control protection.
Installation:
1) Connect the unit between your receiver and throttle servo. But, before applying power check wiring color code to ensure correct polarity.
2) Locate unit in battery box or holder. It is best to keep dirt or water away from unit.
Also, secure unit so it is not loose and allowed to wiggle freely on leads.
3) To setup the unit, turn on the radio transmitter and car receiver. You should see the throttle and steering servo’s operate normally. Also, the fail safe “red” light will be flashing quickly. If solid red, you may have radio problem or not turned ON.
4) With radio transmitter on, push throttle trigger to full brake and hold, not full throttle.
Then, with a pin, push the Set Position button on the fail safe unit. You should feel a one click and a flashing red light indication. For a few seconds, the red led will flash quickly then pause, this pause indicates the fail safe is set to your brake trigger position.
The unit is now set. To check, turn off radio transmitter. Note the throttle servo will immediately move to the brake position set, in this case FULL. Also, a red light will be on.
Solid Red means dangerous operation; Slow flashing red means possible problem or low receiver battery. With either indication (Slow or Solid red), stop operation until interference or battery recharge is done.
IF YOU HAVE ANY QUESTIONS OR PROBLEMS, CALL TECHNICAL SUPPORT.
