Before the start-up of our vehicle, we must carefully read the instructions, as each car may require specific attention for its correct operation.
First we proceed to make the engine running, look for a place outdoors and well ventilated, for this we need the fuel with the nitromethane% recommended by the manufacturer, a bottle to put the fuel in the tank and a spark plug to heat the spark plug.
For the first starts, once the fuel tank is filled, we will loosen the spark plug ¼ turn to remove compression to the engine, we will place the spark plug and start pulling the PULL START with short pulls (to avoid breaking it) and repeated until the engine starts. It is important to remove the spark plug once it has been started, otherwise it could damage the spark plug and tighten it again.
We will leave the car running at idle on a support that allows the wheels to turn freely without touching the ground and in this way the engine will not suffer in its first moments of use. While the engine is running, we will control its temperature, which in no case will be above 100º. Now we wait for the fuel to run out, then let it cool down and we will repeat the whole operation from the beginning, if we do it with 3 tanks, our engine will thank us.
Once the engine is running, when removing the spark plug, the engine stops, it is possible that we have problem with the spark plug, it is necessary to replace it with one of the same numbering (temperature) and be careful with the washer that it does not fall .
The carburation will always depend on the external temperature that we have, and the height (atmospheric pressure), if necessary to modify it, we will do it with the high needle, large jacketed screw located on the outside of the carburetor on the exhaust, and moving it very little, at most 10 minutes from the hands of a clock, less than a quarter of a turn. If the car makes a lot of smoke and throws fuel without burning through the exhaust pipe, we will have to close (tighten) said screw, in case the engine takes a lot of temperature, then we will have to open (loosen) the same screw.
To stop the engine, we must cover the exit of the exhaust pipe with a rag or object that does not let out air, bearing in mind that it is very possible that it is hot.
Once verified that the car responds well to the turns of the steering wheel of the transmitter and the accelerator and brake, we will proceed to place it on the ground.
In the case that once placed on the ground, the car has a tendency to deviate towards one of the sides, by means of the TRIM we can neutralize this deviation, in the hobby cars we will find it in the transmitter (indicated in the instruction manual) , and toy cars, will be located on the underside of the chassis (indicated in the instruction manual).
