I don't ask for the whole real world pilot operating handbook but I think that at least speeds, limitations, procedures and a little bit of system descriptions are necessary if you want to try flying this wonderful aircraft as it should!! I think a project tupolev like manual would be nice.. but, as you are telling me, maybe there's nothing like that on the internet. I've read a small guide from "ubsoft" about the switch description and I watched a video on yt about the startup sequence but yes, it's definitely not enough. Anyway thank you very much for your answer!!
