Koaxial RC Hubschrauber
Coaxial rotor helicopters have two reverse rotors arranged on top of each other. Therefore no additional tail rotor for torque compensation is needed. Above all the tail rotor’s remaining drift (roll) lapses. This simplifies the steering within limited space and indoor, for example in halls. As the rotors are driven by two separate electric motors the yaw axis (turning on the spot) is controlled solely via the rotor’s speed difference.
However it reacts significantly slower than other models with tail rotor what makes flying in wind more difficult.
The boost regulation usually happens speed-controlled and only the lower rotor is partially being linked (4-channel) via swash plate for pitch/roll regulation.
The construction effort is not higher than with the tail rotor construction, but the steering is a lot easier to learn. As a result the 3,5-channel models are comfortable and controllable for the beginner.
3-channel models resp. 3,5-channel models spare a swash plate and the forward/backward flight (pitch) works per a small, vertically working tail rotor. For the 3,5-channel model a gyro ensures a stable tailpiece.
4-channel models by contrast are normally already swash plate-controlled, meaning that the tail rotor is being omitted. Due to the fourth channel these models are able to roll (in other words capable of sideways flight).
Small models up to ca. 50 cm rotor diameter are generally not suitable outdoor (only when there is no wind) for they have very low weight and motor power. Bigger and heavier models can be operated outdoor without any problems.
