OK noted. I understand it will be a large feat to get up to that distance and actually control it but this is just going to he a straight there and back boat no races . Just trying to build a boat able to bring a bait up to a dam and drive it back so all an all a set of binoculars will do for that problem. I'm only looking to drive the boat at 15 mph so not that speedy . Just using 2 motors to produce enough torque to push the boats wight and haul a sizable bait.
