i just deleted everything, sorry for wasting your time, the 2 seat was to give you an idea of the size the thing maybe you can get an idea of the voltages involved.
It is an experimental class airplane , and this would not make anything to compensate for aerodynamic deffects like in the 737 Max, nor really do anything that matters. The system is already redundant, and just wanted to add one more layer for extra security not the reverse.
I am trying to program something to control the flaps of my small 2seat plane.
I won't touch anything that has immediate influence to a human life. I doubt that the FAA (or whoever is responsible in your country for such stuff) will allow such a modification to a plane.
I don't think I would rely on a hobbyist controller and my low knowledge of programming when 1000s of feet off the ground. I'm sure others will concur. But that's my opinion. Good luck.
Just don't. Read up on the 737 max and MCAS to see how badly this can go even when professionals are trying fly by wire stuff.
