. What means when we spoke of a motor 40?

We are customary to handle to liters and cm3 - cubical centimeters -, like units of volume or capacity, and a
to refer us to the volume of the cylinder of the motors - rolled in those units but in aeromodelling the market,
influenced by the most powerful companies, it uses the cubical inch.

Thus a motor 25 is a motor with a cylinder of 0.25 inches cubical.

Equivalence is: çm3 = 0,0610238 16,39 inches cubical 1pulgada cubical = cm3

ADVICE And TRomo SUGGESTIONS

The motor without verifying will not be taken that:

- the motor firmly is assured in the model.
- the helix firmly is assured to the motor.
- the helix is balanced.
- there is nobody to less of a meter, neither are clothes or objects that could originate mishaps; nor there are children to less than three meters of the helix turning.
- the air flow of the helix does not arrive at another aeromodelista, stock market of tools, transmitters or other model airplanes.

• Example: Graupner: The SuperNylon helices do not have to be used when the speed of the ends of the the 180 shovels exceeds m/s. The number of revolutions depends then on the propeller diameter and can calculate dividing constant 3438 between the propeller diameter in meters.

Asi ': A helix 10x6 does not have to turn to more than 13000 RMP and one 9x6 does not have to turn to more than 15000 RPM.
 

To equip the model airplanes with those elements that allow to reduce the noise level .

 Note: If they are going away to make runnings or long sessions of adjustment or tests of the motors, sufficiently to move away of the zone of preparation and assembly.
