Trialsguy I dont think it has to sink but I noticed that the fa would pull the antenna down and wrap up the roots and all. I invisioned putting a rod out on the left side of the pond and just letting it go until it reached the other side but it would probably just crawl out of the pond and end up in a field wrapped around a fence or something HA HA thats if I could figure out how to mount a slow motor on the shore.
Just experiement a little and youll figure something out maybe a coat hanger in a drill who knows.
thanks
