Yes, I received a reply from Erick Gregan, he was very helpful and kind.
Thank you for your answer too.
Just for others to know, the JU52 likes to be a bit rough in the landings, in order to detect better the floor and switch to taxi mode, yesterday I tried (in spite my soul hurt every time

Thank you for the support guys.
