I want to build a tugboat strong enough and large enough to tow my canoe with me in it. Basically just for fun and to say it's that strong. I have already considered buying plans from twotugboats.com but I want this to be my own design. It's gonna be big. I plan to hang a 40lb thrust trolling motor for propulsion (Not scale I know) and a 12 volt deep cycle battery but I have hit a problem. I don't know what kind of esc to use.i have considered the pro boats 50 amp but not sure it can handle it. Any recommendations?
