Hello, just got two of these first one works great super fast .. but the other one was a no go out of the nice box that they come in.. 50/50 shot But i will order more because that is the first from HK that was bad .. cheap but the one that works is good...Worked great good performance on the tail of a Raptor 30 but engine died 5 feet off the ground and got a boom strike and the servo stripped out. The gears in this servo don't hold up good in a crash.Very good servo, precise centering, good resolution, nicely packed, fast. quiet I am using them in a VCTRC500DFC all around. Remember stripping the gears with crashing or hard landings. Although people say there are no gears. Did some investigation and the 1st, 2nd and 3rd gear are 31/11, 49/14, 52/11. I have ordered fut9253 sets and will try when they come in, because same teeth count on them and size, and only 18USD shipped for 5sets :-)Purchased for my HK-600 for both cyclic and tail. Could have used weaker on the cyclic but I am using a DTS setup and figured the stronger torque would come in handy, also nice to have 4 identical servos, easier to stock spares. tight fit in the 600 and had to use a servo plate to space the front 2 out enough to fit but once in it works perfect. As mentioned elsewhere there is some noise when slightly off center, but nothing major. Really cannot beat this quality for $20, I plan to purchase more!!!I got 2 of these servos (Rudder) for use on a Gaui 425 FBL BeastX and also a Gaui 550 fitted with 572XL boom Futuabe GY401 Gyro(550mm Main blades).
I was using a Futaba 9254 on the Tail before It burnt out. These Turnigy Servos perform every bit as good as the Futaba 9254. They are nice and crisp and precise. Best bit is they run at 6V unlike the Futaba so no need for a step down. I am running separate BEC on both of my gaui's. So far I'm impressed. 15 flights no issues still nice and tight. I'm no Professional Hard 3D Smack Pilot but it I have done some 3D with these and tail servo holds up very well.
All in All a good servo for your money.it is very fast...i will how long it will live...i hope hobbyking sell also its gearsI bought 1 servo like this and i ll be using for my heli 550 on the ruder side.
when i make some tests on this I give you details how work this.
(my heli is under construction)Very speedy servo with decent performance for heli tail use but I think the plastic gears let it down. I'm currently testing this servo on the tail of a Trex 600e fbl with the ZYX gyro, response and hold is good but I feel the overall performance is hampered by the flex of the plastic gear train. While there's no actual slop and the servo feels plenty powerful under movement it is a bit too easy to force the servo horn from it's intended position. The best way I can describe the feeling is that it's got a "spongy" hold around center, once you force it more than a few degrees off it tightens up properly and fights back as expected so I'm sure this is down to some flex in the gear train.Good servo and has good resolution. Comes in a nice metal box. It's so fast on my 1/10 drift car that it can follow the bounce of my transmitter steering wheel at neutral when I let it go from max. It's noisy even when the servo is a little bit off from neutral. Sometimes it's unable to pull itself back to neutral if just a tiny bit off. It's either the servo or my car's steering linkage.
Been doing well so far with no other problems. Hopefully it lasts. Get this one it's a really good deal and cheap to replace!Un excellent servo tres rapide et tres fiable, il respire la qualite car il est tres silencieux et precis. J'en ai achet 3 et je suis totalement satisfait par cet achat. Ils sont destin un helico de taille 600 mais sans vol brutal.
