ok, i disassembled an rc car and took out the insides. Im planning to make a boat out of it. My plan was to put the 2 motors, from the toy car, on either side of a platform( this will act as the rear end) with motors apart like 3-5 inches away from each other. Now, when i turn one of the motors on, will it make the boat turn the other way? like if i turn the motor on the right will it made the boat turn left? I assume that if i turn both motors on, it would go straight? Can i maneuver the boat with the motors positioned like that?
YES, IT WILL WORK FINE , THAT IS ACTUALLY THE DESIGN OF MANY RC BOATS, LOKAT THEM ON EBAY , MY OLD BOAT WORKED LIKE THAT
You probably want to reverse the polarity on one of the motors – don’t have the shafts/props spinning in the same direction. Real boats with two motors have what is known as “counter rotating props”. For the turning, it is more like a thrust. I am not certain of this, but both motors should spin inward instead of out ward. You can experiment with this though. Just mount them, and reverse the + and – wires to the battery. Hope this helps. Don’t expect the boat to behave the same as a a car.
