My Bench is a mess. I am building a 143 Porsche 956. I bought a bunch of 10X10 X20 mm 6 pole motors. The profile of them is square. They develop 16000 rpm @ 12 volts, and have good torque. They have excellent braking properties for such a small motor, so they are well suited for slot cars. The most drivable motor I have come across yet and recent test times with the lastest chassis has resulted in some best laptimes for me.
