I bought 2off these servos to replace 2 (other make) servos that changed centering as voltage dropped in flight! These KST servos are absolutely perfect with 2s LiPo giving very quick response -- buy them !!

I bough 4 KST servo, and one of them start to make problems, after letter to Neil, i sent video and took 50% discount for new servo.

Comment by: PeterStrange Problem Cause Identified
The source of the problem described below has been identified and it is caused by the motor coming loose in the case and slipping downwards causing the motor pinion to drop out of the gear train. See this link - https://youtu.be/HrQGWu3Ra74
The motor is held in with loctite and can be reglued. KST recommend loctite 496. Check your motors are secure particularly after a bit of a knock.
Comment by: PeterStrange Problem
Using four of these in a Flipper. After a throw the rudder went hard over with the rudder torsion spring. After getting it down the rudder servo motor was running continuously and the output arm could be moved as though it was not connected to the gear train. Pulled the top off and the gear train was fine showing normal function. Put the top back on and servo works fine. This was a v5 servo.
Review by: Protsenko KirillBest servo for this price
This is the best servo with no compromises, precisious, metal, high power. Servos were delivered fast to Ukraine and packed good.
Review by: PieterThank you KST
Thank you KST, you just cost me a not even 6 month old Snipe SN because of a sudden servo freeze on the elevator servo.
The servo freeze occurred just after launch and remain frozen until it was manually pushed back into position.
This was a X08 V3 servo. These have a reported occasional boot problem (one in a thousand) when powering-up. Always check the servos respond after switching on.
Review by: Oleg BovykinBest DLG Servos
These servos are best for DLG. KST X08 are light, metal and High Voltage.
I use servos with 2S battery without BEC and direct connection to the receiver.

Probably the best dlg servo out there for the money. Been some issues reported recently so the factory revised the KST 08 servo and these are now fresh stock at Hyperflight.
I had no issues with the V3's previous and so far this latest revised V3 is work just as well as always, highly recommended servo all round in a dlg.

Very good servos, v bad reports on pervious designs
Looks like they have remedied the problems
Slight bit of backlash in the gears but the pros out weigh the cons
The only servo that would fit in my 7.5 mm thick wing
Review by: danny p
Received servos in good time however one was faulty (twitchy) so I had to send it back for replacement at my own expense with no offer of reimbursement so a bit disappointed.
Two out of three servo horns are next to useless very sloppy fit, at least the ones i needed were okay, servos have a little play in the gears not slop free but acceptable not sure I would recommend.
Review by: FelixKst x08n for #boom dlg
Quick delivery and superduper service! The servos fits perfectly in my new #boom dlg from Jim Aero. Thanks from Norway.
Comment by: AndersPThat ! small
I know perfectly well how much 8mm is, and still it's amazing how small this servo is when you hold it. For its size the torque and speed is really good. I haven't had time to test it live since the plane is not ready yet. The servos will go inside a moulded stab and be connected to the elevator surfaces. Build quality of the servo seems to be top notch and the size allows for fully built in servos in even the thinnest of wings. A really nice product!

great little servos
Review by: Jon
Replaces an X08 v2 that died.
I dropped it in the wing and was pleasantly surprised to find a slightly longer servo lead. Works as expected, and props for the wide voltage range.
Review by: RobertRKST X08N
Perfect fit for a Blaster 3. Their lack of lugs, flat sides and wires that exit from their bottoms allow them to be butted together for a straight, tight fit.
