It appears you're providing a step-by-step guide for assembling and customizing a multirotor drone, specifically detailing a project with Pixhawk autopilot and a high-quality G-3D gimbal. Below is a breakdown of the text into its most critical points, categorized by major task areas: wiring, mechanical assembly (canopy and G-3D gimbal), and balancing. ### Wiring 1. **Pixhawk Wiring** - Consult pages for advanced Pixhawk wiring charts for detailed connections. 2. **ESC Wires Replacement** - Replace wires from Q-Brain or Hobbywing Skywalker ESCs with 20cm long ones for a better connection range. - Solder directly to the module input and use HXT 4mm bullet connectors on the output side due to Pixhawk’s power module having XT60 connectors that are not compatible with your chosen flight battery. 3. **Taranis TX Compatibility**: - Use analog battery voltage sensor input to FrSky D4R-II from Taranis TX for both battery level indication and for compatibility reasons. - The digital voltage can also be read through Pixhawk's telemetry output by using a FUL-1 adapter. ### Canopy 1. **Additional Canopy Creation** - Use a vacuum forming machine to create a custom canopy. - Design the model with 15% honeycomb infill and print it for use as a positive mold. - For DIY vacuum forming machine plans, search online (google). 2. **Vacuum Forming Process**: Clean cuts are important; for curves use a hooked carpet cutting blade, and fix points can be made by using a leather hole punch. 3. **Mounting Canopy**: - Secure the canopy in place firmly and evenly. ### G-3D Gimball 1. **Mounting**: Instead of a sluggish bottom piece, mount G-3D gimbal to the body using a 2mm thick aluminum or carbon fiber bracket between the bottom and body support pieces. 2. **Balancing Tool**: - A tool for adjusting the balance can be made by printing the provided PDF-file on metal/CF sheet. - Adjust and secure correctly with an additional self-tapping screw through bottom, bracket, and mating support pieces in the body. ### Final Steps - Secure wiring in place firmly and even using foam pads to avoid movement. - Balance for a precise Centre of Gravity (CoG). This guide shows significant details and care given to various aspects from initial design considerations like material choices and vacuum forming techniques to precise adjustments needed for ensuring balance, stability, and proper operation. The extensive use of resources including online charts and forums suggests an ongoing process of learning and adapting best practices in drone development.
