I've been fying with these in my Trex 600n for a year now. Still working really well and just gone V-Bar using same. Wow!

voila enfin du BLS a un prix competitif,ces servo sont exeptionnel en precision au cyclique,sur mon Srimok 90E KASAMA ils font des merveilles,je les utilise avec un beastix sans probleme en 6Volts pour du 3D,plus de 600 Vols a leur actif et toujours rien a redire...
Merci beaucoup HK!!!

This is a very good brushless servo, even slightly better than the futaba brushless servo's.

It's made by MKS and relabeled Turnigy by Hobbyking.

And for a great price! thank you Hobbyking !

This is, in my opinion NOT are full or real Brushless Servo. I would call it Semi-Brushless



Its got a Brushless Motor, for sure. But the Servo Amplifier used is a Version for DC-Motors, linked to a DC-BL Converter. (2 pcb inside)

Thats why the Servo behaves like a Servo with DC-Motors.

Elektronics seem to bee build for 7,2V, but above 6,3V it shows massive overshoot and centering problems/jittering.( Just like DC-Motor servos do)



The Poti inside looks like a cheap Pertinax-type, most probably this will be the lifetime limiting Factor. But the Performance shown at 6V is very good, no Play in Gears, good centering.

Fast enough for Trex600.



But technically ( Electronics) far behind a Futaba BLS, which is Full BLS including Brushless Amplifier.

MKS Turnigy BLS 950

Hab heute meine BLS 950 bekommen.

Ein erster Test - Die Geschwindigkeit haut mich nicht vom Hocker, aber es luft unaufdringlich, das Getriebe ist bemerkenswert spielfrei.
Max gemessene Stromaufnahme ( gemittelt) 0,8A. ( Spitzen mgen etwas hher sein.
Auffllig ist auch da es, wie viele Digitalservos auch im Leerlauf kurze hohe Stromspitzen zieht. Mein zum Testen verwendetes HK-Billig BEC gibt dabei Gerusche von sich, die lauter sind als das Servo.
Mit 1000uF Elko dran ist das weg.
=> Solche Servos an BEC`s nie ohne Pufferelko betreiben.
Da die Futaba neuerdings fr 7,4V zugelassen sind, wollt ich wissen wie das mit den MKS aussieht.
Ich habs geffnet, und auf der 2.stckigen Platine u.A. einen FR6461 Servocontroller gefunden :
www.kcsemitech.com/uploadfiles/.../2009031817014912.pdf
Dieser ist fr 7,2V zugelassen. Da KCS ein rein chinesischer Halbleiterhersteller ist, wrd ich das nicht voll ausreitzen.
Beim Betrieb an 7.0Volt zeigen sich massive berrschwinger und Nullpunktsprobleme. ber 6,3V hinaus scheint es nicht brauchbar.
Die Geschwindigkeit steigt aber merklich.
Die Erklrung offenbart sich beim Blick auf den verwendeten Servocontroller. Dieser ist ein Servocontroller fr Brstenmotoren. Nachgeschaltet ist eine Wandlerplatine DC=> Brushless. Dies erklrt warum sich das Servo wie ein Servo mit Brstenmotor verhlt. Der Vorteil von BLS-Motoren, Steps wie ein Stepp

excellant servo from HK. i just got few days back and they are quiet and centering is very good, and not having any play in gears. i have put it on hirobo tarbulance D3.

The BLS950 work fine, dead band 1us or less.
Speed and torque like announced.
Gear do not have play, although is a little to tight.
But the consumption at stop is too high,
something around 90mA,
witch would can require a battery of more capacity than usual.

Definitely the best digital servos available here. They have great holding power, resolution, center extremely well and are very quiet for digitals. Gearbox is smooth and slop free. Highly recommended.

ok,fly these on cyclics on a Compass 6HV for a summer now. Still running on 4.8v and well over 100 flights on them.

GREAT SERVOS! still running strong , no slop at all in them.

Using futaba super strenght (black) arms with them. Flying hard to really hard 3-D at 13.5+- pitch , 50c 12cell.

They are holding great, without any weakness in any of the set of 3.Would buy more no questions asked.

I have 3 Turnigy BLS950's fitted to my FBL Gaui X5. They centre well, operate really smoothly and run real quiet compared to the DS610's I had. I highly recommend them for any heli setup, quick and good holding torque at 6V!
