Don't know more details about this DIY "WWII Hotas" (for lefties), but show nice ideas, modified car seat, extend stick (probable with DIY gimbal) with angled grip, throttle/button box with rotaries for trim (notice decals):
Probable made with USB card like L.Bodnar BU0836 and grips from old stiks.
Looks better for IL-2 that these F/A something HOTAS.
This VRInsight panel is useful (and bit expensive): push and toggle buttons, 6 rotary encoders (white knobs), 6 axis (2 knos, 4 sliders), 4 way siwitch (HAT).
