1 1:8 SCALE NITRO POWERED TOURING CAR RTR INSTRUCTION MANUAL *SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE. SAFETY PRECAUTIONS! This radio control models is not a toy! - First time builders should seek the advice from people having building experience in order to assemble the model correctly and to produce it's performance to full extent. - Assemble this kit and places out of children's reach! - Take safety precautions while operating this model. You are responsible for this models assembly and safe operation! - Always keep this instruction manual ready at hand for quick reference, even after completing the assembly.

2 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 buy hot plugs, like the MC-59. In your box you will find.. # Bottle, spout top # Red C size glow heater Glow Fuel 20% AA Batteries ( 12 pcs ) #10211 NiHm Flat Pack 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 batteries. Recommendation 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.

3 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. Don 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. Clear 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!

Dry with lint free towel and a quality masking tape. These can be purchase or a hair dryer. (Keep your hand clean.) at your local hobby supplier. Use the curved scissors to trim the body to the guide lines provided on you body shell. STEP 4 Use masking tape on the inside of the body to STEP 5 Paint the inside of the body! STEP 6 mask out your design and windows prior to Use a spray color suitable for polycarbonate. painting. Press down the edges! (Paint the darkest color first.) Allow the paint to dry for at least an hour! Remove the masking tape and protection film from the outside of the body. STER 7 Apply the decals to the outside of the body. We suggest use a hobby knife to cut them out. STEP 8 Use a hobby knife to cut holes for the fuel tank, STEP 9 engine and antenna tube. Make two 7mm holes for the body posts; one at the front and one at the rear. Drill two 7mm holes in nylon wing. Using the measurements provided in the instruction. Use the clip provided to secure the wing to the wing mount posts. STER 10 Mounting the body to the buggy using the body clips provided.

33 ENGINE BREAK-IN AND TUNNING (BREAK-IN THE ENGINE BEFORE DRIVING THE CAR!) Choose a wide clear outdoor location with low dirt and dust. Set the car on box or holder with wheels off the ground. Turn on radio and car. Make sure throttle is at idle position. Fill fuel tank and set master engine needle. Prime fuel line and Heat glow plug before pull starting engine. When started, let engine fast idle for two tanks of fuel. OPTIONAL OFNA CAR STANDS WOOD BLOCK TUNING AFTER BREAK-IN 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 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. 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. Idle adjuster screw & Barrel Stop Lean Rich

36 SETTING UP ADJUSTMENT OF THE CHASSIS CLEARANCE Use 2mm hex wrench to adjust 4x10mm set screw in front lower arm. (FRONT) Use 2mm hex wrench to adjust 4x10mm set screw in rear lower arm. (REAR) Place the model car on flat surface. Use 2mm hex wrench to adjustment the chassis to it's minimum clearance. We Suggest: 10mm in front and rear. Adjustment of the right and left-side are the same height. SET-UP OF THE FRONT WIDTH * Use a 2.5mm hex wrench to adjust length of the front lower steering ball will make the front become width or narrow. Adjust from the lower steering ball. (FRONT) ADJUSTMENT OF THE FRONT AND REAR CAMBER (Positive) + Adjust from the upper steering ball of the front knuckle arm. 0 - (Negative) (FRONT) 154mm Center FRONT TOE-IN AND TOE-OUT SETTING The rear camber adjustment can made by moving the turnbuckle rod on the upper arms, clockwise or anticlockwise. Toe Out 0 Toe-In (Positive) (Negative) (REAR) Adjust the length of the front steering rod to change the toe angle. Making the steering longer will make the front tires become toe-in. Response will be slower. Making the steering rod shorter will make the front tire became tor-out. Response will be quicker. Steering Rod
