But what ELSE should you do? This is a game, but a simulator game. It simulates real life. Just look up the RL HOTAS of any given plane, which takes roughly 30 seconds of google-fu, replicate that on your HOTAS, done.
If anyone isn't willing to do THAT LITTLE, I don't know if this is the right game, tbh.
That said: T.16000M, Warthog and most other controllers DO have a default keybinding, don't they? Using VKB for a long time now, can't quite remember. Not that it mattered, because I just bound RL controls to my old X56.
