I just built something I had to get right on the first try because messing it up would be more than a little dangerous. Endless fitting and testing and re-thinking before committing to building it. A little cheating was involved, I built a 1/17th scale test setup to ensure that all the electrical bits would work.
Yes, it works. Test rides three days ago, first real trip yesterday, 65 km there and back on a single charge. Write-up one of these days, have to collect all the material.
