An essential tool for all pilots of eletric model-helis. From the values of the engine-output, pinion-size and the sizes of the transmission-gears, the speeds of the main and rear rotor can be calculated.

Important: The values represent calculated, thus theoretical values and can be different from real-world values. We cannot guarantee accurate values, nor can we be held responsible for personal injury or damage to your helicopter.
