This Serve is SuperStrong. As far as now i have no Problem with it. Works well as a cheap Steeering Servo on my SCT 2WD Kit. Lets see how it works over time.super kraft, alles gutStrong and and Good Quality.
Good Replacement for Reely(Conrad Modellbau Germany) Steering servos.
Very good and fast and strong using it on heli sceadu 50 no problems noted fast shipping thank you HKLow quality product, in case you care about you plane I strongly recommend to use other servo than this one.
I have 4 faulty ones during last few month, it looks good and works lovely till it stops !!! The fault happens randomly regardless the servo use, rudder , throttle or other use.
I have used it for a trainer which means it is overpower and not suppose to stop working.
I'm very disappointed .......
Thanks to HK support team I received a refund however I had to spent hours to fix the planmelhor servo que ja comprei ate hoje!!!!
tenho no meu racer cat 60 , estou usando com bateria de life sem bec , sao de excelente qualidade essa parte prata e um acabamento de aluminio que ajuda a dissipar o calor do mesmo , muito bem centralizados recomendo a todos!!!!I bought 8 of theese servos. They are pretty good quality. Have all metal gears - some are made of brass and some are made of solid metal. Electronics is also good, but one wire is pressed to the engine housing so I had to put some isolation tape between the motherboard and electric motor. ALSO, SERVOS HAVE VERY POOR CENTERING - they stay uncentered around 3 millimeters to one or the another side. Very poor.Great servos. Good centering, no gear slop and amazing torque. Using mine on 6V: quick servos! Will definitely purchase more.Just receive mine, all 3 servo perform well on the benchtest.
Good speed on 6V, just a bit warm after 1 hours ( no load).
Very good centering so far with not much play around the zero ( pretty amazing)
I manage to find a buddy code on hk RCsearch and pay only 7$...
Cheap for a 9kg servo...time will tell , i will post update after few flight.
Take care guys
