I didn't log my hours but I'm sure I have 50+ hours into the job. The tight tolerances made it interesting for sure. In the end it took a little Dremel tool work to get my rudder sensor to work. The L&S drive appears to be very high quality and I'm looking forward to seeing it in action. Did you get the locking solonoid model? I'm considering adding that or the Eco-pilot to reduce the amp draw. It sounds like you have a top-notch system! Enjoy!
