From the project

A complete open-source flight controller architecture for the STM32H743. Includes custom Betaflight target files, bare-metal silicon bug fixes, and a ruggedized carrier board blueprint optimized for dual SPI BMI160 IMUs and heavy-lift multi rotors.

This document outlines the complete hardware architecture, propulsion system, and Betaflight tuning parameters for the 10-inch Mark 4 endurance cruiser. The PID and filter configurations are specifically optimized for smooth, long-range flight dynamics and heavy payload stability, utilizing a custom STM32H743 flight controller.

These PID values are tailored for the high inertia of a 10-inch frame. D-gains are set slightly higher on Pitch to combat the larger moment of inertia, while Feedforward is kept moderate for smooth, cinematic stick feel.
