Tail rotor diameter
Please enter a value in meters.Tail rotor rpm
Desired rpm of the tail rotor in rounds per minute.Tail rotor blade chord
The depth of the blade has an effect on the lift produced by the blade.Pitch travel to left
Pitch travel to right
The angles of pitch available in both directions.Pitchoffset
This is the pitch angle at center position of the tail rotor stick. If the Automatic calculation of pitch offset-option is active, the software determines the offset necessary to compensate the main rotor moment during hovering outside the ground effect. An entered value in this case will be ignored.Positive pitch revolution mix
Negative pitch revolution mix
This corresponds to mixing a tail rotor pitch increase from increased main rotor pitch in order to compensate main rotor moments. A value of f.e. 0.5 at 6° main rotor pitch will add 3° to the tail rotor pitch. These values may be monitored using the Data display during simulation.Gyro sensitivity
This value defines the sensitivity of a gyro and should be adjusted to an extend that the tail will not swing during fast forward flight.Delay between gyro and tail rotor servo
That value describes the delay between detecting a turn and generation of a correcting signal. Usually, 0.02s is a suitable value. Fast gyro/servo combinations may call for faster timings. A long value is not suitable as it would generate a tendency of swinging making a precise flight impossible.Servo respond time for 45°
The servo speed influences the delay and relates to the swinging tendency.Tail rotor linkage play
This value generates the contrary of precision and supports the swinging tendency.Automatic calculation of pitch offset
If the option is active, the software determines the offset necessary to compensate the main rotor moment during hovering outside the ground effect. A pitch offset value in this case will be ignored.
