No strange buzzing noise. It's a new 1/16th spectrum servo so I assumed it would be decent. It returns true with no splines missing. If you turn on the tx and Rx and put load on the servo saver it's stays kinked one way.. I think it must be a poor design. It's not even like it's working hard, this thing is tiny lol. I could understand it on an xmaxx
