WWII
Bf 109 pedal - practical, beautiful
IMO - Spit are not practical for sim use other than replica pit builders... Same for Hurri/P-51/P-47 due his operations way
Modern Jet
F-16 - just because is most wanted.
Civil
Cessna and Boeing
Helicopter
Maybe the UH-1, unsightly but common in various helicopter types
Slaw,
And such a generic WW2 look, with two axis but brakes on bicycle style lever to attach on joystick?
For Spit, Hurri, Blenheim, Lagg, il-2, Yak, Pe-2, La5...
Or a economical 1 axis version (similar to WKB Pedal-T concept, not his operation system - press instead push).
