Product Overview
RC & Digital Servos
Ultra-Lightweight 1.5g Micro Digital Linear Servo (L & R Pair)
The 1.5g Ultra-Micro Digital Linear Servo Pair is specifically designed for weight-critical RC models, ultra-light indoor 3D planes, micro helicopters, and specialized linear actuation projects. By utilizing a high-efficiency micro coreless motor and a direct-drive lead-screw mechanism, this linear servo provides exceptional positional accuracy and smooth proportional stroke in a package weighing just 1.5 grams.
Symmetrical Left & Right (L / R) Configuration
To ensure clean aerodynamic installation and balanced weight distribution on micro airframes, this product comes in dedicated Left (L) and Right (R) mirrored configurations. This allows symmetrical wing mounting for ailerons or twin-rudder linkage setups without needing complex inverted mechanical geometry.
Precision Lead-Screw Linear Drive
Unlike traditional rotary horn servos that require complex Push-Pull linkages, this linear servo converts motor rotation directly into linear travel via a precision screw shaft. This reduces backlash, eliminates linkage flex, and delivers instantaneous control surface response for aggressive indoor 3D aerobatics.
Key Advantages & Integration Features
- Direct 1S LiPo Operation: Designed to run seamlessly directly off a single-cell LiPo battery (3.7V – 4.2V) without needing a heavy external BEC.
- Universal Micro Connector: Pre-wired with flexible silicone wires and a JST-SH 1.25mm 3-pin connector, fully compatible with standard ultra-micro receivers (e.g., Spektrum, Flysky, FrSky micro receivers).
- Compact PCB Chassis: Built directly on a high-rigidity fiberglass PCB frame with pre-drilled mounting tabs for easy installation using micro screws or foam-safe adhesive.
