Review: My go to servo now. - Probably wouldn't use anything else in my planes but these at this price point. They are super reliable and super powerful. They operate smoothly and have little to no feedback, chatter, glitching or lock ups. I have a couple dozen of these servos in various planes and not one has failed, some have even been through a few nasty crashes
