Very good servo and affordable priced. This may OEM of Bluebird servos, Made BMS-383DMS to high voltage. Good quality, stiff, precise, silent. This is DIGITAL servo and control period is high about 400Hz.
I installed these for V-tail servos on Strega-3m full carbon Hotliner, supplies 6V from Turnigy 5V/6V 5A Heli-UBEC for Lipoly (6~16V).
Another pro. point is height. Total height is low and easy to install/linkage in a slender fuse.Just bought half-a-dozen of these little beauts.
Have only tried them out on the bench, but can report that they all work perfectly.
They are nicely presented and build quality is apparently high, to judge by external appearances.
Really pleased, so far. They'll be going into a couple of gliders ... I'll report back when I've flown them for a while.
Absolutely brilliant servo!!
I've got this fitted to my Losi Mini 8 and although its slightly smaller than the stock one its twice as fast and carries more torque!!
Its also able to run at 7.2v so i've got it connected to an external BEC (my esc is only 5v) and its ultra quick. Its also smooth and centres precisely every time. This operates without fault :)
For the price, under 15 you honestly can not go wrong. These are a brilliant servo.
One thing i would suggest if running this in a car is to run a servo saver so you don't cause any damage to the gears on a heavy impact :)
Its the same fitting as a Servox & Futaba - 25 tooth.
I will say this puts A LOT of more expensive servo's to shame!These are nice solid, strong, fast servos. They are a smidge heavy though. The only really bad thing is the poor quality and poor selection of included servo horns. A servo this good should have a better assortment of horns.Nakon kupnje 4 kom. serva iste sam odlucio ugraditi na HobbyKing Katanu 1500 EP. Uz preinake sjedita serva na Katani serva se odlicno uklapaju na model. Serva su vrlo brza i dovoljna jaka za model raspona 1500 mm i teine 2600g. Proizvode lijepi zvuk kod pomicanja, centar serva bez uocljivih nedostataka.Mocen serwo do Hydro-1 polecam. Uwaga jedynie na zabezpieczenie prze4d wilgocia serwo ewidentnie nie szczelneFantastic servo's. I will not buy analouge any more, HV is the way to go!!!
Very strong servo even on small stick movements.got these servos in a 450 pro i set up for a friend, with a align 3G flybarless unit.
very smooth and well fast
cant really tell any difference from the savox 257
so very goodServo is quite nice, fast, works, well with my Orange 7c FAST receiver. Not sure I like the open bearing on the top it is a place for debris to enter. Servo feels warm after a minute of use. Using it on Elevator and Rudder on my 2.65m KA7 sailplane. The two crowns on quality is because of the way the case is put together, two very brittle bolts screw into weak inserts on the aluminum heat sink. So far the servo has performed well on a LiFe pack.I have unwrapped only one for testing so far and I am really impressed. The build quality is second to none, the metal gear set well lubricated and super high quality and the circuit board is directly mounted to the base of the motor and feedback pot so no stray wires at all. Once again the design and construction look excellent. I tested the servo using a HK servo doctor and found the following. At 5v I found the speed to be 60 degrees/0.12 sec no load which is to spec. The dead band and centring was the real surprise. Just 2 micro seconds and as close to perfect centring. This is amazing for the size/price and class leading. I gave it 400 cycles and there was no sign of any heating up. Subject to no nasty surprises these are the very best mini servos I have seen. The spline is for standard Futaba servo arms. I will post again when I have them flying for an update.
