Received my Moxie continuous servos from lowpricerc.com last night and took a quick look at them. Pretty decent little things for $3.40! Metal bushing on the output shaft, decently fast and reasonably torquey. Construction inside was not too bad… no solder blobs bouncing around to short things out (can be a problem with some of the cheaper servos). I ran them head-to-head against the Parallax continuous servo and they are very slightly faster and have a little bit more torque so I’m happy with them. The pot for tuning center position with a 1500us servo pulse is actually nicer than the Parallax and easier to get set. The Parallax servos can be a little twitchy. Remains to be seen how durable they are.
