Generalities about radio control helicopter parts assembly

The mechanical assembly of each radio control helicopter is amazing.

The radio control helicopter assembly can be interesting. The meshes are delicate and the coarse grains that pass through these mesh shirt may not always fit between the piston. Therefore the engine tends to clean them out but unfortunately unlikely, a model engine operates most of the time away from the soil and dust, the component that can scratch a shirt is the charcoal deposited in the cylinder head, we assume that it is a mixture of dust and charred, and the oil should be cleaned periodically.

This is why the perfect engine operation takes place when the fuel enters the carburetor to regulate pressure (depression is a relative concept with respect to atmospheric pressure, there is always pressure in the fuel even if little) and the air is also to regulate pressure in these conditions, unless the balance is altered, engine failures aside, work always the same.

This radio control helicopter balance can be altered by changes in regime and the carburetor should be able to manage them, or by changes in operating conditions, soil or air, the mechanic must know to adjust the engine to fly not to work on the floor. All sorts of changes lead to conditions that cause a defective pipe, a leaking carburetor or of poor quality, improperly installed tank or inadequate fuel

All these factors are those imposed by the good or bad functioning of a healthy motor, or even be able to destroy in a second. The carburetor is also important. The needle, on land, must be regulated for a mixture slightly rich, fine-tuning a radio control helicopter engine on the ground only leads to a malfunction in the air and their rapid deterioration. Even in any other type of engine, it will be better to opt for a more powerful design. For a four-stroke engine rule this is even more acute: carburizing rich forever.

In usual racing radio control helicopter engines pressurize the tank through the engine crankcase pressure, this is very simple but has the disadvantage that the engine should not be run at idle thing ever if race does not matter in normal flight is unthinkable. There is a device called a regulator that is able to regulate the fuel flow by reference to the pulse from the crankcase of the engine, some engines incorporate it internally, but the device exists separately and allows pressure to feed a conventional carburetor.
