KST X10 V8.0 10mm Slim Digital Metal Gear Wing Servo

The KST X10 V8.0 is a slim digital wing servo for RC gliders. Its CNC-machined aluminium case is only 10 mm thick, so it fits thin wing sections, while hardened steel gears and a coreless motor deliver up to 10.8 kgf·cm at 8.4 V. It is made for F3J, F3B and F3F aileron and flap installations.

Key features

• Wide 4.8–8.4 V supply range (rated 7.4 V): runs from a standard 5–6 V BEC or straight from a 2S LiPo.
• 9.5 kgf·cm and 0.12 s/60° at the 7.4 V rated voltage.
• Hardened steel gear train on two ball bearings.
• Programmable, with soft start.
• Potentiometer position sensor and ±50° travel (100° total).
• 28 g with a 15 cm lead.

Torque and speed scale with voltage — 6.2 kgf·cm at 4.8 V against 10.8 kgf·cm at 8.4 V — so an HV supply gets the most out of it on heavily loaded flaps. Check the 30 × 10 × 35.5 mm footprint against your wing pocket before ordering.
