Yeah and the $10,000 is just for single prop. ATPL costs like $70-100k so yeah like Yurgenst said, this setup is definitely cheaper.
Also this isn’t the craziest setup I’ve seen. On Reddit years ago I saw a F-16 pilot recreate his entire cockpit complete with the FLIR displays and a real F-16 yoke but managed to make it collapsible. So he could stow it into a chest like thing that his wife approved of haha. He was like “I just really love my job, I want to keep doing it when I’m not working”.
