Arrived well packed and work as they should, good deal and would recommend and also would buy again

Working well

Used these in a ground based (thankfully) project. 12 servos. 4 plugged into the board overloaded the 3 amp buck converter at an idle. Found some the pulled too many amps. A few completely dead. Some get hot. All are extremely weak. Your milage may vary, but there is no way i would purchase these again for any purpose let alone in a flight application. Of the 12, 5 are still in project. They are getting cycled out as i write this. Consider Miuzei instead. So far they are working smoother. On teardown they are not even MG90 servos. All gears are plastic but the one you see on the outside.

Although many people are saying there are some plastic gears in there, the main one is metal. It has worked well for my RC plane projects, and have taken a beating, but still work just fine.

These servos are better than other for some reason. They are quieter the plastic case appears to be a higher quality but has the same mg90s stickers. I’m confused but I’m going to use that. Buy again button as soon as the need arises
