I find that the collective requires far too much power to rise and afterwards it is very difficult to do a good hover, because it immediately rises too quickly and picks up too much speed.
So far I find it difficult to manage.
For example the B47 helicopter is not easy, with a very normal behavior, the collective in hover mode is in 22-30 and I use 1/3 of the collective.
But with the bell 206 I almost reached the end of the collective race for the hover.
Edit : 21h46
After new tests I find that I made 2 errors for the engine start, this allowed me to improve the hovering start.
But what still bothers me is that the collective quickly rises to 70% while 30% max for the start will give more margin to the handle and it would arrive at about 1/3 of its race, thus giving more margin to smoothly handle the hover.
