I did it all myself with a band saw, dremel and a file. The panel part itself took about 30 hrs. The entire project, repanel, rewire whole plane, install autopilot, convert to electric flaps and trims, install pmags, rebuild both wheel pants, rebuild both brake calipers, and program everything took 2 months and about 150 hrs. It was definitely worth it. I would never go back to manual flaps and trims.
