Default kershaw designs 550 motors

any body tried one? there only 10 bucks
heres the specs from there site

Low RPM / high torque motors. High torque from long 550 motor can, 5 pole (instead of 3 pole) armature. 6,600 RPMs at 14.4V. Good from 7.2 - 30V.

i had a pair of the 700's in a emaxx. they had some balls,but ran really hot, even geared lower than kershaw recomended gearing, ended up burning up one, he replaced it free. then went brushless

6600 rpm @ 14 volts would make for one excruciatingly slow motor..... That's only ~460 kV. For comparison, the average 35t motor is ~1500 kV.

that is about equivalent to a 100t motor. Super slow, even on 6s lipo.
