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..
