Rc helicopters- Engine and propeller facts

When focusing on the rc helicopters engine and or propeller, manufacturers do not give much advice. It usually mean the maximum consumption in amps that can tolerate and maximum working voltage in volts or if the number of LiPo elements is the same, another curious fact that it provides is rpm / v revolutions which will run idle as the voltage in volts applied to it. Begin gathering data to become a master in rc technology.

What happens with the characteristics of this mode? The answer lies in the helix, modern engines have a very wide operating band propellers can put larger or smaller, few or many elements and the manufacturer is limited to indicate the limits of your appliance. The power supplied by the rc helicopters motor depends on what prompted the propeller, if you are coming to burn your chances if requested propeller causing a power exceeding its limits.

The maximum power is the product of the maximum intensity that supports the supply voltage and a motor support 30 amp LiPo allowed to use three elements provide a power of 342 watts (30x11, 4), but this power only get if you put a propeller to absorb that power. The rpm / v is an indicator of the type of propeller that will best suit our model, a high value of 3,000 or more rpm / v will be suitable for an electric turbine (EDF) a value of about 1,000 to 2,000 rpm / v will be adequate for small rc helicopters.

Most often, these models have light values below these engines that are designed to move a few rpm propellers important in models of increasing size, the lower the number of revolution per minute per volt. Luckily for us and because of the improved technique of manufacturing these rc helicopters engines, there is an existing and approximate relationship between weight and power that we can use to bring our choice of model engine to propel, to give final empirical figures.

Motor zero may be a great option, too. It is impossible for a helicopter to fly well with the motor to zero, but this is something much rarer than it sounds, the option to zero motor is surprisingly enough. It appears more successful if you do not have the opportunity to make measurements or tests necessary to use the engine options. Look at the most rc helicopters outrageous models!
