@sanderux yes, experience with the 85 but also quite a few other comporable hitecs, (several hundred over the last year or so). It's a numbers game. They're not the best servo but not the worst by any means. They are a really good one and with an even better warranty. Over the past 18 months I have about 30 varying hitecs that have to go back but that's probably in the 5% range and of those 30, probably 60-70% were user error and not broken from coming from them. Just likely a bad batch you got.
