Great servos, great service thanks Neil
Review by: McTor4
Fast service. Great price.
Review by: AndrewSKST X08 v5 - a quality product
Quality that will be enjoyed long after the price is forgotten! Always nice to find a product that is built up to a quality, rather than down to a price, and yet is still affordable. Served up impeccably by Hyperflight, not least in the accurate pairings of gear to models, which I found exceedingly useful shopping from the other side of the world.

Fast delivery, very good servos.
Review by: NickOh so fast
OK. I admit it. I've not fitted them yet,but I know they'll be good.
JUST a quick note of praise for hyper flight. I ordered yesterday I think around ten am and the servos are here today (UK to UK) service. That's service. Thanks.
It means I'm flying tomorrow, forcast is good.
I think the man is Neil, so Neil thank you your a star.

Great little Servo with Big attitude, use this in the majority of my gliders.
Fabby service from Neil at Hyperflight

Good product + Fast delivery
Review by: A. SutherlandKST X08 Servo
I am using several of these servos and recommend them for DLG models. For me they work perfectly all the time.
Review by: Toshio Kimuragood!
I think it's the best match for F5J and hand lunch.
Review by: Jim HathawayF5J Fuselage servo
More than adequate power for a light glider. Perfect accuracy.
Review by: Tony
Looks a nice servo, beautifully manufactured in aluminium rather than plastic and appears to work as expected. My only worry is that the exposed motor and wiring might be suspect able to water damage should it rain or land on wet grass. Probably just me worrying rather than anything really to be concerned about.
Review by: Ali SutherlandKST Xo8
I have been using these servos for some time now because they fit perfectly in my DLG'S, also operate on a wide range of voltages and are powerful beyond my requirements, my personal choice!!
Review by: AnonymousBeware of reverse battery
I bought these to replace a set of 4 which I had just installed but not used. When I was setting up the radio I had accidentally plugged the battery into the receiver the wrong way. The servos were completely ruined within a second. Expensive mistake!
Review by: Jim HathawayProblem solved by KST X8
Just couldnt get the backlash out of the elevator on my DLG until I fitted this servo. Problem solved. I've got these on my Shadow and Supra, but never appreciated its quality quite so much until now.
Review by: Mark PassinghamKST X08 V5 HV Servo
These servos don't really need another review as they seem to be the standard 'go to' servo for DLGs.
So just a a simple review: Wow.
Review by: Anonymous
Tiny powerful servos at an affordable price.
Review by: AnonymousKST 08 SERVOS
Excellent service. Really nice servos. Looking forward to installing!
Review by: Ian McConnellKST X08 V5
I needed servos for a RCRCM Sunbird which has very thin wings. The KST X08 fitted a treat. Still waiting to fly the Sunbird to see how they perform.
Review by: KevKST - X08 Servo
Fabby service every time.
Review by: Mark
Switched back to KST X08 for my latest dlg as I want to use a 2s lipo and my current servos were not 2s compatible. Used plenty of X08's before from my first Blaster 3 that I had off Neil, through many other planes to my current Auri, and they have always been rock solid for me. Usual high class service from Neil, I wouldn't shop anywhere else.
Review by: Steve YorkKST X08 V5 Servo review
Superb servo which I bought (x4) for Precision Aerobatics Addiction X build which I wanted to keep the weight to a minimum. Plenty of power for this application and about 1/3rd the weight of recommended servos without sacrificing speed and power.
My one criticism is that by extending the throw of the V5 they have eliminated any possibility of extending the throw as available in my Taranis radio where I can extend throws up to 120%. This is a problem because it means that even normal 100% throws, if you apply a subtrim, you lose it at the extreme - there becomes a dead part of the stick for which there is no more servo travel.
Once this is realised, it can be worked around because the V5 has so much throw that it can accommodate subtrim by slightly reducing transmitter throws to (say) 80 or 90% giving a little leeway for the subtrims.
Very pleased with this tiny servo.
Review by: Rich EriksonGreat price
Even though I am in the US... I got these servos fast and at the best price... I am keeping Hyperflight bookmarked for future purchases for sure!
Review by: Ali SUTHERLAND.KST X08 V5 HV Servo
I have 8 off these in a couple of DLGs , my latest 4 are in an AURI I bought a few weeks back, for me these are excellent servos at the price with perfect centering using 2cell Lipo
Review by: SimonKst x08
Fantastic servo and great service
Review by: Richard EdmundsVortex 3 arriving!
Have been buying KSTs for a number of years and they have never let me down. These are the preferred option for the DLG community, and look superb, although they have not been fitted yet. Bought the optional pull/pull pulleys - nicely made
Review by: Anonymous
I've recently changed over to MKS but bought these to fit the NRJ servo tray. Very happy with them, work great, precise and 1-2 compatible.
Review by: Paul
very good servos! recommend
Review by: Keith BurrageVery nice!
I bought this servo on Neil's advice to replace a FrSky c2110 that had failed on my Loola DLG. Bit expensive but performance, resolution and centering are noticeably superior to the FrSky offering. Runs faultlessly on one cell Nice one Neil, I'll be back!
Review by: RichKstxo8
Nice perfect yet to test them in flight but look impressive
Review by: James Garrick
Nice servos, haven't fully tested them in flight but accuracy and speed great so far in the plane. More than I wanted to pay for a small servo, but worth it definitely.
Running them on 2 cells to remove the weight of the BEC in DLG.

Good solid and tight, very precise. Not the quickest but that is no problem for me !

Very good servo for the price using on the sprite & the Circle Dancer 3600 great little servo.
Review by: JohanExcellent servos!
Very good resolution! Measured only 1us deadband on mine V5 servos. Very pleased with the quality and I have converted to only KST 08 type servos in Indoor models and MPX Parkmaster. You need good servos to enjoy the precision of your Control input.

Have had 3 of these go awry over the past month.

Welcome advice as to how best to fix it (thought I had, but not in every case).
As usual Neils team does great service. They can't be held solely responsible for product failures.
Review by: Lou BrooksGreat Servos
A really nice, small servo that works great for DLG and smaller gliders. Works with 2s lipo voltages which works great with my Graupner receivers.
Review by: Anonymous
fast service. great price.
Review by: Ralph
Wonderful servo and a bit lower in price, without sacrificing quality, than the competitor.
Review by: Mike VosSuper Servo
Great servo. very light. Wide voltage range makes it an excellent servo to run of 1 or 2 cel lipo directly.
Review by: AnonymousGreat little servo and Great service
Great little servo, and of course you receive the awesome service from Hyperflight.
Review by: Roger Sanders
This is a truly impressive servo. It is amazingly tiny, built to the highest quality, and is very light. It has plenty of power and is reasonably fast. Highly recommended.
Review by: PhilipKST X08 V3 HV Servo - 8mm 8g 2.8Kg.cm.
Happy with the purchase
Review by: GliderBillHyperflight service
Neil has given me excellent service. I have recently e-mailed him twice with product enquiries, even before placing my first order. Neil responded within a few hours each time, with very useful replies to my questions. I have now just received my first order for KST X08 servos. They arrived in excellent condition and very promptly. The shipping charges to Canada were very reasonable, esp. when compared to international shipping charges levied by some other model supply companies.
I have not yet tried the new servos as they will shortly be installed in a new Blaster 3 that is about to be built.
Review by: Dav Var
nicely built servo, very rugged for its size. First class next day delivery - thank you Neil.
Review by: Martin G
These servos are tiny, too small for my intended use as MiniVec aileron servos but I will be fitting them into my Longshot dlg when I get the time.
Further update to follow.
Review by: PaulBrilliant Service As Always From Hyperflight
Ordered these revised versions from Neil a month or so back. Received my order as soon as they came live on the site. Fitted to my Alula Trek for super smooth and rapid response using in DLG mode. Many Thanks!
Review by: Richard SwindellsWorst service ever from Hyperflight
Hyperflight refuse to sell servos to me, so I have to import these from Hong Kong.
Completely ruined my preparation for the F3K World Championships because of the delay. Great support for your national team ?
Richard runs the Flyquiet forum. He banned me from it a few years ago without notice. It has always wrinkled, so when he placed the order I emailed:
If you would care to reinstate my neil stainton FlyQuiet forum account I will be happy to send this order.
Richard's reply was:
If you would be so kind to issue a refund.
- Richard Swindells
He didn't reply when I asked why he wouldn't reinstate the account. I will of course be happy to supply him if he stopped excluding me from his forum, and posting partial comments.
Review by: Olivier Leroy
Good servo, good service, fast delivery !
Review by: Joris
I have these servo's in a Avionik F5D. The first version had problems with a fully charged 2S Lipo. Now I have installed the new v3's in the racer and after 8 flights I can say they are performing very good. Very little slop and fast on 2S directly. Hopefully they will last.
Review by: Cliff StoneTraditional?
My recall replacement KST X08's arived the other day. These are the 'improve version', They were originally destined for a 'save weight progect' on my Avalon (4m Ava), so I was pleased that I could now continue.
What suprised me when I opend the box was the servo cable has been moved from the end to the bottom of the case, making traditional bearer or tray fixing much simpler. The X08 simply drops in as a snug fit giving more meat for the srews to bite on.
As I say 'traditional', modern glueing in is easy and often practical but the way I wish to mount the servos dictates a tray and screw job, the way I used to do it in the 70's
A very nice touch IMHO, simple and effective, as the bottom of the case is cut away, the wire exit is not interfeared with by structure. Be a good idea to show a pic., on the web listing?
Thumbs up from yours truly . . .
Review by: Rex Grace
Price and specs on this servo are great. Performance not so much. I bought 2 of these servos and 1 failed out of the box on a 6V system. The failure and subsequent recall of these servos has caused unwanted delays in completing my Super Supra.
Review by: Roy
Ive ordered 4 times from hyperflight now, every time product has been dispatched promptly and arrived here (New Zealand) within a week or so. Great service, great products,helpful info if needed. My first choice for my F3k stuff.
Review by: Anonymous
Nice servo with accurate movement and holding power
No problems running 2S lipo
Servo wire could be a bit longer, about 25 mm.
Review by: Heinz
Perfect...the deliverytime short, price o.k. and a very good processing qualityof the servos. The KST x08 are ideal as aileron servos for hand launch gliders. Just adjusting fast and suitable with 1 or 2S Lipo.
Review by: hrrPrecise but rather slow...
Tested them on the desk only so far. Feels well made, very strong for its size, barely noticable slop but a little slow at low supply voltage (1S).
Still one of the better servos at this size...
Review by: RickNice small and accurate
Have not yet flown with the servo's but tested them on the ground. They look precise rather quick and strong.
Work great in my MPX system, but they were not stable on my servo tester. These digitals probably need quicker update rate than 22 msec. I use 14 msec on my RoyalPro.
We have to see how they last in the Wings of my Helios-2 DLG.
Review by: Tjarkofirst test X08
I ordered these for F5D.
Very nice and small and a good supply of control arms.
Unfortunately not "completely slop free".
They also run a bit rough. I prefer MKSDS65K, as long as they work reliably...
