I was reading in Big Jim's booklet about brsushed motors. Ok, if a person would have a really good 540 motor , a 12/3 and to get more torque would take the shell off another 540 and wrap and solder the shell on. I take it from BJ, it would show less rpm but increase torque, am I correct? I have plenty of 540's and thought putting it in a balsa 22" mono with a Oct. 630 prop for the H### to see what happens. Replies are welcome. Winter gets to long and boring!!! Oh yes, thanks!
