Overview
The Kpower DMC026 is a coreless digital servo for RC airplanes, helicopters, cars and boats, including tail/rudder control on 450–500 class helicopters. Its brushed coreless motor, machined titanium gears and aluminum mid case combine in a compact 36 × 15 × 29 mm body. A 25T output spline and voltage-specific torque and speed ratings help buyers assess mechanical fit and control requirements.
Features
- Brushed coreless cup motor with digital servo control.
- High-precision machined metal gears, specified as titanium.
- Semi-aluminum construction with a CNC-machined aluminum alloy mid case.
- 2BB bearing arrangement and 25T output spline.
- PWM, TTL and RS485 control compatibility.
- Three-wire lead with a three-position connector.

Applications
- Helicopter tail/rudder actuation: Intended for 450–500 class helicopters, with a 25T output spline for the control linkage.
- RC model linkage control: Actuate mechanisms in RC airplanes, helicopters, cars and boats using the compact body and machined titanium gear train.
- Drone mechanisms: Provide servo-driven linkage movement where a compact coreless digital actuator is required.
- Smart-home mechanisms: Move small controlled mechanisms using the compact servo body and supported control interfaces.
- Medical-equipment mechanisms: Provide controlled mechanical movement using the coreless motor and metal gear train.
