After using the plastic-gear 9g version of these motors, I had quite a bit of trouble figuring these out.In the end, it turned out to be mainly my fault. The main issue I had, was trying to figure out how to properly use them. With my previous electronic setup, I found that when I issued movements to the servo, it would work at first, and then it would spin indefinitely (and would refuse to listen to any PWM commands).This confused me for two reasons: 1) I didn't understand why the motor was not listening to the PWM any more and 2) I didn't understand how the servo was continuously spinning in one direction (despite seeming to not be a continuous motor).Turns out the following:What was happening was that my power supply was fairly bad, and thus, when using these beefier servos, the power supply could not keep up. This, I assume was causing the servo to crash, stop reading the PWM signal.I read reviews of other Servos that advertised "continuous 360 rotation when powered off" so that tells me this motor is probably something similar.I also read another comment from someone saying that continuous motors have a tendency to continue doing the last received command.So in my case, I think what was happening was the following:The servo was given a signal to move to a position.The microchip would crash and stop reading the PWM.The microchip loses connection to the PWM and defaults to continue what it was doing before (moving). And thus, the servo doesn't stop spinning.Anywho, once I swapped out the power supply, I didn't have the same problem.I noticed someone else in the reviews mention this spinning behaviour, so hopefully, this is helpful to someone.
