You are introducing a complicated technical topic … This is not for starters. So please explain what your critics is about. What BET model are you talking about… what would your BET model mean for a simulator (in terms of benefits ? accuracy ?)
Maybe you just read this topic of last night and conclude there is no propellor model at all ? You assume throttle setting T is just pulling MSFS planes forward with force a T*C or something ? I think that is not the case. You seem to know more about the internals of the MSFS propellor model, so please teach us. What are the shortcomings…
