Have you guys seen my site's build thread on my robbe engel conversion with suntech auto leveller and depth control?
It's at http://magpieyachts.com/building7.html
and http://magpieyachts.com/building8.html
Have a looka nd see how I did it. It has 15 nimh sub c 3600s and I now get an hour of running at scale speed with 3 or 4 static dives to the bottom and back etc. I'm very happy with it. The whole build took me 3 months and was a blast!
