The difference between the R22 and the Cabris’yaw control on the approach to the hover is simply the greater need for anticipation of the large and under some circumstances more sudden pedal movement on the Cabri. The gain in safety of the fenestron (you can’t walk into it) and the fact that it looks nicer is offset by the fact that it is less efficient ( about 17% I have heard) due to its smaller diameter. To offset this the fin is angled to unload the fenestron in the cruise. As you slow down on the approach, this effect is lost and hence has to be replaced by quite a large pedal movement. If there is a crosswind from the right, the fin stalls quite suddenly, exaggerating the need for a large pedal movement.
Simply put, the required pedal movement in the R22 is smaller and relatively linear. On the Cabri, it is larger and not linear, but like most things you get used to it.
