These servos arrived 2 days after I ordered them. A very quick and excellent service with tracking.
Can highly recommend.

Great hv servo I got a pair for my new f3f vantage from ccm Great service from hyperflight next day delivery spot on thanks
Review by: AnonymousNot fit for purpose
Purchased August 2022, The servo arm moves around center by 1.75mm each way under power, the whole internals move, useless is the only word. having many KST servos and being very happy with them this is an absolute shock.
Neil offering me a 50% store voucher to return them was an even bigger shock having bought them the day previously!!! He also suggested i took it up with KST!!!
Think twice before buy here.
In my reply email actually wrote:
a) You return the servo, we test it and if we agree it has failed and has not been abused we will send a replacement. We can only offer this for servos that have their lead, have not been opened, and have not had the mounting lugs removed.
b) Or we can give you a discount voucher code for 50% of the servo cost, and you buy a new servo using our web site using the voucher code.

Lovely looking servos but donít centre so precisely as my cheaper align 450m. The rudder was always of centre so changed them out.

Fitted these in my last 2 gliders. Well made, reliable & compact size, plus plenty of power. Great service from Neil

Excellent company to purchase from. Lightening delivery experience
Review by: Lloyd Davies
These are great servos for the fuselage on high performance gliders. I just about managed to get them to fit a strong Freestyler 5 and 6 but had to Dremel some of the fuselage where the servo corners are. One thing to watch out for with these is not to let the receiver battery drop to a very low voltage say less than 3.5v-4v as the servo output does a full 360deg turn which can damage linkages that are connected.
Review by: Richard EdmundsHarrier
Ideal for my new V tail Harrier. Like the idea of no potentiometer, so await similar 10mm wing servo
Review by: Bob RGreat little servo.
On test these are very accurate. Perfect for V tail F5j model. Great servo.
Review by: AdamKST MS-320 - small piece of art.
It's really difficult to add something more positive than was written by others modellers.
Simply this servo is fantastic - small piece of art.
I think that contactless technology will be implemented by KST soon to all servos produced by them :-)
Many thanks for quick delivery to France - even when Covid19 stopped all Europe I received my servos in 5 days.
Review by: Brendan TownsendLOVELY servos!
These KST MS320 servos exude quality in their construction and performance, chosen from the crowd for contactless feedback on a special project (modified WW2 aircraft instruments for a professional simulator) demanding premium reliability and longevity. I just wish they were more readily available - particularly brushless + contactless in small and large flavours. If they were, I'd be spending thousands.
Review by: John TurnbullKST MS320HV
I can only really repeat the other reviews and say they are quiet, fast and a quality product at a reasonable price. Just as important, the service from hyperflight has been excellent.
Review by: John BarrowThe Best 12mm servo
I bought 2 of these for my Leprecaun after having trouble with a pair of 8mm servos (not KST). They are perfectly sized for this model and so smooth. I will always look for contactless servos in the future. I also have a pair of KST x12s on the same model and you can feel the difference in the action.
Review by: Dominic MessihaExcellent Servos
Beautiful little servos! Center great, quiet and very fast.
Review by: YevhenKST MS-320
Very good product. Fast delivery.
Review by: AnonymousKST ms320 HV servo
These contact less servos are quite superb,powerful,quiet and accurate with no slop,add to that the extra reliability gained from the hall sensor positioning then why would you ever use anything else for elevator control?
I look forward to KST bringing this technology to ten mill wing servos, I will feel a great relief!
As always the very best service from hyperflight .
Review by: Mike Evans
Initial impressions are very good, looks and feels like a quality servo. spec is great.
