Parameter menu point D
At Parameter menu point D the HeadingLock gain for the tail can be adjusted. This gain comes into play when the tail gyro is operated in HeadingLock mode. It determines how hard the tail gyro tries to maintain a given rotation rate from the transmitter. If the HeadingLock gain is too low,
pirouettes will be inconsistent during fast forward flight or in crosswind conditions and the helicopter will slowly drift on the vertical axis when in stationary hovering flight with crosswinds. If the HeadingLock gain is too high, the tail rotor will respond delayed to fast directional changes and the rudder stick control does feel very inprecise. So only adjust this parameter as high as necessary. It is also possible that the tail will bounce back slowly after stopping from a rotation and commute gently while hovering or flying around. Please note that very often this also may be a sign of a stiff tail mechanics, slop in the tail linkage or an inadequate rudder servo! The tail rotor system in this case does not react as precise as necessary and hinders the tail gyro from working properly. If you cannot increase the HeadingLock gain higher than “very low“ or “low“ it is very likely that there is a mechanical issue.
Parameter menu point D only adjusts some part of the tail gyro control loop. First of all, you must adjust the tail gyro gain in the transmitter and use it to switch the gyro to HeadingLock mode.
- Before adjusting the HeadingLock gain always try to find the maximum amount of tail gyro gain by flying around and using the tail gyro in HeadingLock mode.
- After adjusting the HeadingLock gain it might be necessary to readjust the tail gyro gain! Both parameters interact to each other.
The currently selected value is indicated by the Status-LED color and state. Move the rudder stick into one direction until the Status-LED lights in the desired color.
| Status-LED | Control behavior |
|---|---|
| off | user defined |
| purple flashing | very low |
| purple | low |
| red flashing | medium |
| red | high |
| blue | very high |
The option “user defined” allows you to choose your own setting that can be edited by using the StudioX software bundle and the separately available USB2SYS interface.
