Have you ever taken apart a vaccum cleaner motor? There are no brushes. That is because instead of the wound of the wires being on the armature, it is on the can! The magnet force alone turns the armature, without brushes. Since Aveox primarily dealt with electric aircraft applications, the rpms are extremely high. Some one, a while back, decided to install one in a r/c car. 6 and 7 cells provided ample speed, but had long run times. So, they just kept adding more cells, and the Aveox speed controller handled it. The most I seen on them is 12 cells. I read that there was even more applied, but they melted the diffs or blew tires. With the introduction of the new sub-c cells, you can mount as many as 12 cells and lose the weight, making the car even faster! I wished I had the RC Car Action Mag, or even my Home Computer, but I am in Iraq and there other racers that can back me up on the Aveox systems. Problem is that they are expensive and the come as a set; speed controller and motor. Blow either one, and you're through.
Now I seen Drag cars built on 20 cells and the only thing controlling the power on those things is a switch! Once contact was made with the 20 cells and a 8 turn, single wound motor.......just keep the wheel straight, or you lose the car!
