Spent a little time looking at the water rudder connections and decided to just eliminate one rudder… never needed more than one on any other float plane… then do a standard pull-pull connection to the other. It’s all rigged now. Looks like this:
Kept the eyelets on the end for adjust-ability and used Kevlar thread for the runs just because I had a small amount on hand that was probably not enough for anything much larger. I haven’t tested it yet so will have to get back with update #3 with a report after a field test… or is that pond test?
