Hi,
In the ancient Bundeswehr jeeps, this was very simple to implement using a Bowden cable, which simply pulled the gas pedal down. So, something like a manually adjustable "idle stop" for the accelerator pedal.
So, with simple mechanics, it should be possible to achieve this, but I have my doubts about whether it's actually allowed.
Maybe it's better to have it work directly with the + and - function of the speed sensor via a microcontroller...
To use the F22 thrust lever, you would also need to install a thrust augmenter...
Best regards,
Jan
