General Information
The AW139 Helicopter Collective Grip build guide provides everything required to construct a highly detailed and functional replica collective grip for helicopter simulation applications. Designed for home cockpit builders and flight simulation enthusiasts, this project combines 3D-printed components, readily available hardware, and electronic controls to create a realistic collective control system.

This guide is divided into three key sections:

Parts Guide – A complete list of components, hardware, and electronics required for the build.
Print Guide – Recommended 3D printing settings, materials, and preparation instructions for each printed part.
Build Guide – Step-by-step assembly instructions covering mechanical construction, wiring, and final installation.

The design focuses on achieving an authentic appearance and operational feel while remaining accessible to builders using modern desktop 3D printers. The project is suitable for integration with a wide range of helicopter simulation platforms and can be customised to meet individual cockpit requirements.

For the best printing results, a high-quality FDM printer is recommended, though the design can be produced on most well-calibrated 3D printers that support standard PLA or similar materials.

Whether you're building a standalone helicopter rig or adding rotary-wing controls to an existing simulator, this guide will help you create a professional-quality AW139-style collective grip using easily sourced parts and proven construction methods.
