OK, you are the man and I bow before your wisdom and electrical knowledge.....

Like I said, although I can wire a complete house and make basic electrical repairs, Im not an electrical expert down to the ohms and amps and I was clearly not trying to be such in my comment. It was a general statement that made the general point for a general purpose.

Im expecting you will dissect this too, but what I was getting at and apparently poorly explained was that if you use a larger motor it will draw more amps (current, blah blah blah) so you may need a larger speed controller and it will also eat up battery capacity a lot faster so you need a battery with a larger capacity (same output voltage but holds more milliamps).

Is that clear enough for your liking?
