No matter how many cells we go to, people will always burn up motors trying to get the most out of the .05 package that they can. We can go down to 4 cells, and the motors will just go down to 4 turns! People burn up GM3's all the time and it is a 27 turn motor. It is just tuned to the edge of existance. 1/12th scale cars dont burn up as many motors because they are very light and have to be geared and driven conservativly to make run time. Look at real racing. They burn up engines all the time. Same problem, they are trying to get the most out of a given package that they can.
