1 servo out of 4 does not set exactly to the 0-position

OK, but could be better.

Servo qui semblait bien ! Mais au bout du compte beaucoup de jeux dans les pignons. À na pas utiliser dans un modèle rapide, j'ai du flûtage sur les gouvernes. Dommage car le rapport qualité-prix semblait être bien.

VERY Impressive Servo!

Nov 29, 2021

These servos are a PERFECT substitute for much more expensive 'Brand name' servos with the same specs. So good infact, that I imagine they are manufactured under the same roof. Hardcore Italian Alps style composite glider aerobatics? - Go for it!!! KST 25T metal arms are a perfect fit. These are flawless servos so far, & mean business. Thankyou again HK!!! Absolute top notch winner!

Acquistati 6 pezzi tutti funzionanti senza nessun difetto sono molto robusti e veloci e hanno una gran potenza senza giochi di ingranaggi... Vedrò con il passare del tempo come andranno per adesso 5 stelle senza dubbi

Reliable and strong servo to an unbeatable price.

Compare this servo with any other servo on the market,and you will find that nowhere do you get so much for such a fair price. Minimum slack and precise zero positioning.

Nice servo but useless rudder arms

Aug 11, 2020

Very good servo, seems to be a rebranded KST Servo. Nice housing and very good metall gear.
But the servo horns are completly useless. HK delivers a 9kg servo with slowflyer horns! This is a bad joke! The horns are very tiny and have a mass of micro holes. No chance to mount a standard clewis.
I had to buy suitable horns for about 7$ each. With the original horns you cannot fly this 9kg in a glider.
Overall the first negative experience with HK servos.

Very good servo

Jun 04, 2020

I am using it for a robotic application where size and force is important. It worked very well. I was burning other slim wing servos a lot. This one have been working for months now w/o any problems. I've even tried to increase the rotation angle by pushing it beyond its spec. I was able to gain little more but not much. It is pricey but worth it for my case. Another good thing about this servo is that it does not have a mechanical stop like others, so you wont easily burn it if your rotation is restricted somehow during the first installation.

Excellent Servos that are perfect for my Slope Soaring Glider. Like they were made for it...install was a breeze

Must have got a dud

Jan 02, 2020

Price spec and initial appearance were all good. The servo centred well and looked promising.
I fitted it inside the fin of a 3m glider but while I was setting up the controls the servo suddenly became erratic and moved the rudder from side to side in a juddery and noisy manner.
I had been a while finishing the glider build so didn't bother sending it back.....I binned it and put it down to being a dud servo. My other Turnigy servos have been great so I suppose malfunctions can happen....however if this becomes a common event then there may be a problem with this particular batch of servos.
So all in all a neutral but honest review.
