CHA DS06 Servo - 1.8Kg.cm 0.07s 6.2g 7mm

I purchased 6 of these for an f5k build as they seemed perfect spec wise and they are, well the ones that worked anyway.
3 out of the 6 are completely dead and a 4th has a really bad glitch so will not be used.
Now I'm going to add I had modified the leads of the servo's (killed my warranty) but this is kind of standard to get rid of unwanted excess wire and connectors, I'm also going to add I'm a electronics/communications Eng: so I'm not bad with this kind of thing.
2 of the servos are faultless, perfect, really fast and I mean really fast and they re-centre every time back to perfect centre... so why do 4 fail and 2 don't please read on ill make it brief lol.
So I did some investigation and found that dry joints on 1 were to blame a friend of mine had this exact same fault but the others were a little more complicated.
The potentiometer internal of the servo has a fault, either a crack or break of the internal bored (i'm not pulling it apart to look) it'd need a microscope to find it, I do have the equipment but i'm not overly bothered as I know what the fault is and couldn't fix it resistor even if i opened it i'll just change the pot at some point or keep them for spare parts.
Now the amazing bit..... All of the above and more was reported back the CHA them self's and the response was nothing short of fantastic and there's many companies that could learn from it.
The reason...... not a quibble infact offered to send me some servo's as replacements, I didn't have to ask or beg they offered straight away now that's customer service, Patrick at CHA was so helpful and did everything he said he would do no Bulls*** said he would sort it out and get back to me by the Monday Am and did, my servos are on there way to me.
This sort of thing does not happen often and is totally out of the control Hyperflight and the most part CHA themself's.
all's well that ends well.

Look good on bench test, very quiet. Can't say how they will perform in the air, but I don't anticipate any issues. These are going to go into my kit bashed Slite V2, which is currently under construction.

Cheaper than MKS HV4070, cheaper than KST X06, but really just as good. Bonus, the pulley for KST servos also fits these servos. I have them in an NRJ, a Strike 3, and a Deviant. Excellent performance on 1S HV Lipo. No double centering in any of them, would recommend to anyone from sport flyer to competition pilot.

Lots of choice, fast service and delivery, I recommend it.

Very happy with my previous purchase of 3 servos. The 2 in use currently do the job perfectly so I've bought another to give me a pair for the next build. Took a while to get here but that's not uncommon with international shipping.

Superb service as usual halfway around the world to NZ. These tiny servos look well made and bench test as expected. Soon to be fitted to an F5K model so haven't used them yet and can't comment further.

Arrived promptly as always. 👍

Came fast, in small bubble letter one servo.
Product great, precise, robist, fast, thin.

Better prices and lower shipping cost than a close US supplier.
