9g Continuous Rotation Micro Servo

Nothing fancy, but low price, and it can push a fairly decent load, so I'd recommend it

We ordered some servos that we intended to hack for continuous rotation, and when the time came, they were not hackable :-( Seems like that happens a lot. You don't want that to happen at the last minute. These worked great. Thanks!

I bought a bunch of these servos about one year ago and they were great. Speed control needed some minor calibration, but that was expected. Hardware calibration was done with a flathead trimpot flush with the rear of the casing. However, I recently ordered these same servos. Now, the trimpot has been moved far inside the servo housing, and is a phillips head. A small philips had to be inserted through a small hole in the casing to access the trimpot, which was mounted at an awkward angle within the motor. It was much more difficult to calibrate, and thus use, these servos. Otherwise, the servos have good speed and torque, capable of driving a small robot. Wires are slightly weak and prone to breakage if appropriate strain-relief measures are not taken.

I originally purchased these from Amazon, being a novice to the tech scene. When I received that order, they were not what I needed. I was directed to RobotShop.com by a more experienced tech person and was more than thankful. The RobotShop.com site helped me get exactly what I needed, and the shipment came very quickly. I will be using them again for future purchases.

Tiny and speedy, but impossible to get a steady stop position set, it drifts all over the place. I am going to have to add a relay to shut off power to the servo when I want a full stop out of it.
