Rescue/Stabilisation is imprecise :

What to do if your Rescue or Stabilisation modes are not precise?
  1. Very important is to check, whether the Position and the Swashplate parameters are configured correctly. If not, these modes can't operate properly. Make sure that in the Diagnostic tab all directions correspond with real stick movement.
  2. Check if the unit is aligned in all 3 axes. Alignment error should be approx. in 1° range or less. You should mount the unit precisely in respect to the helicopter' frame. Use only one provided adhesive tape. The unit should not flex or move in any way - mounting should be rock solid.
  3. Rescue and Stabilisation can work in nearly any condition. But in case that your Vibrations are exceptionally high it can't be guaranteed. You can check vibrations with Spectral Analysis in the software, especially Y - Aileron axis, where there are mostly the highest.
  4. Helicopter was tilted during initialization or after initialization (it was on the side or upside down for a while). If you move with helicopter after initialization, make sure that the swashplate is level and collective is going up when the rescue is engaged.
  5. Helicopter is equipped with a cooling fan that is producing ultrasound frequency. Fans from HobbyWing ESCs are known for this. This has a great impact on the precision of Rescue and Stabilisation modes.
If any of these requirements are not met, then you can observe with increasing flight time bigger error/imprecision. So in the start all will be OK, but at the end of the flight it may be worse.
In case that the model is tilting to the same side during activation always, then the basic servo settings are not correct.
Please verify that the swashplate is perfectly leveled when Servos/Subtrim (tuning) is enabled. During setup it is necessary to use the Cyclic Leveler tool.
