I have been building model boats for years and am currently working on a series of Chesapeake bay work boats put out by Wye River Models. next summer I plan to start work on the Chesapeake Bay Buy Boat. the model plans are done in 3/8 scale and I plan on transposing them to 5/8 scale and making the model an RC boat. But, I need a little help. I can find drive trains for comparable size model trawlers and tug boat models, but little information on what type of RC transmitter and controllers are needed, as near as I can figure I need to be able to do the following, Throttle, transmission fwd/rev, rudder, do I need a two or four channel RC unit for that and will I need additional channels to turn on running and deck lights? I plan to use two Li ion batteries which can be wired either in 6V parallel or in series for 12V but am unsure what the relative advantages are for either system. Any help would be welcome.
