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.

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.

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!
Comment 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.

Good servo, good service, fast delivery !
Comment 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.

Nice servo with accurate movement and holding power
No problems running 2S lipo
Servo wire could be a bit longer, about 25 mm.
Comment 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...
