Speaking of difficult software, i have almost 25 years of experience with conputers, building, support, etc, even wrote some very jank custom solutions at some point.
But the esrly virpil software was a headache, i bricked the firmware on my throttle at least five times before I figured how to do it the correct way, fortunately it defaulted into bootloader and you can try again.
Its become a lot better since then.
