CenteringLovely looking servos but don’t centre so precisely as my cheaper align 450m. The rudder was always of centre so changed them out.

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.

HarrierIdeal for my new V tail Harrier. Like the idea of no potentiometer, so await similar 10mm wing servo

KST 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.
Thank you!

LOVELY 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.

KST MS320HVI 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 Barrow
The Best 12mm servoI 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.

KST ms320 HV servoThese 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 .
