I built an accelerometer for my 80 cc Suzuki when I was in high school, but then I was not a typical kid.
I can't say that I spent a lot of time looking at the artificial horison when I was taking flying lessons, but hey, anything that works is a good idea.
I'm building a display for the steering column that shows what gear I'm in (and generates logic signals).
Could a vacuum gauge do the same thing for you, perhaps one with a bar readout?
