Thx for the track.
nullThe slope here is more than 15 degrees.
I took control in your track and tried myself. It helps to keep some collective in until the skids touch the ground completely. The ground contact behaviour contributes here. It is hard to tune the code for that and the influence on some things like friction on different ground types seems not possible.
Hard to say. I think it depends on speed and trustvector/flapping how much you need. At least the video shows that it needs at least some counter pedal
If throttle is full open gov is active if it is at 90% it is not but it is a lot of throttle for the helicopter standing on the ground. What do you expect if you toggle between this positions?
True, which speed? it might come together with other effects due to lowering speed? There is the tail rotor blockage effect at low speeds or maybe the induced inflow effect on empenage.
Does the torque needle increase?
