Unfortunately this servo is almost useless because of a large dead band. That is when it changes direction, it moves a long way to reach idle point. It will cause control service to flutter in flight substantially.Arrived in good time, well packaged. Good solid feel to these servo's, arms fit well, movement is responsive. Used these to replace the old servo's in my bushmaster; which already has an upgraded motor and flies quite aggressivley so there is a lot of strain on the control surfaces. These servo's responded very well. I will be buying more of these units.Diese Servos sind fuer Flugmodelle nicht geeignet, die Stellgenauigkeit ist viel zu ungenau bzw viel zu langsam. Und mit viel meine ich auch viel, und zwar so richtig viel!6 bought, only 2 are working properly. one of them is very unstable at a fixed position. two others have a neutral which vary depending the rotation sense. The four item unstable are unusuable. i do not recommand this item.this servo's casing seems to be stronger then the last one I bought. I use this on my 450heli with ikon flybarless unit set at 250hz and works great. Holds and centre's well and not noisy3 from 4 servos that I ordered had an awful centering. one was working OK with good speed and less gear slope. The other three were for the trash. They were more than 5mm way off center when moved the transmitter stick in center position.Fast, robust and reliablethese are great little servos for the money. survived a couple crashes with no stripped gears. gear-train is a little sloppy after much use but they still seem fine in my heli.from 4 servos I have ordered in two different orders 2 are OK but the other 2 have a centering that is more than 5mm off with just a 17mm long horn. 50pcnt faulty in two orders, thats a shame. This servo is fast even on 5 Volt and has also very less gear slope for a metal gear servo. But I will not order that Servo again, the possibility is too high to get another faulty one.One out of the 4 I bought turned out to be a bag. The movement was not
linear would suddenly move a lot. HK please improve your quality control. The other three work perfectly .
