KST X08 Plus Servo - 5.3Kg.cm 0.09s 9.0g 8mm
Description
It is especially good for ailerons on F5J gliders, electric racers, and all models with thin flying surfaces. Despite being only 8 mm thick the powerful coreless DC motor and gearing provide good torque and high speed. The X08 Plus can be operated from a voltage as low as 3.8V (1S LiPo) or as high as 8.4V (2S LiPo). KST servos have excellent geartrain machining tolerances, and this servo is completely slop free, and equal to products costing twice as much. Despite not having an -MG moniker this servo has metal gears, and is very tough.
The KST X08 Plus's high torque, good speed, and 8mm thinness make it suitable for many high performance glider, pylon racers and EDF applications. With up to 5.3 kg.cm torque the KST X08 is appropriate for F5J, F5D, F3J and many types of high performance models.
The extreme reliability and performance of these servos also makes them very suitable for use in film and motion picture industry special effect departments. They are also used in robotic, drone, UAV, UAS, academic research, military, and other highly demanding applications.

Fantastic little servo hv I got this servo for the flaps on the tjirc screamer, great service from hyperflight next day delivery thank you
Strong servo, good service
I ordered 4 KST X08 servos and promptly destroyed them by inadvertently reversing polarity when I plugged them in. Neil was very helpful I diagnosing the problem and then getting 4 new servos immediately shipped. He goes well beyond what I’ve come to expect from online businesses by always responding to inquiries immediately and providing rapid service.
Great little servo was used in my Phase 5 for rudder/elevator.
Fabby service from Neil at Hyperflight always quick delivery
Great service as usual 👍
Great servos I’ve use them in my Magnus 60” slope glider as only 8mm servos will fit in the ailerons
