Core Features & Benefits
1. F4-Grade Cost-Effective MCU with Sufficient Performance for Micro Models
Powered by the APM32F411 main control chip, its computing power fully covers the flight control needs of small drones and mini fixed-wing planes. It runs Betaflight open-source firmware smoothly, supports basic PID tuning and filter settings, and meets daily freestyle flight and racing practice needs, providing stable and reliable F4-grade flight experience at an affordable price.
2. Same High-Precision Gyroscope for Stable Flight in Small Bodies
Equipped with the industry-standard ICM42688P 6-axis gyroscope and accelerometer, it features low noise and high vibration resistance. Combined with targeted optimized firmware algorithms, it effectively filters out high-frequency vibration interference from micro airframes, delivering stable and smooth flight attitude and precise control feel, enabling small-size models to achieve excellent flight performance.
3. Streamlined Practical Interfaces for Clean & Simple Assembly
Interfaces are ultra-streamlined for micro RC assembly needs, retaining all core flight-essential interfaces. The dedicated ELRS receiver port supports plug-and-play without soldering; 1 camera + 1 VTX port meets basic FPV flight needs; 2 servo ports are compatible with mini fixed-wing models. Less commonly used configurations on micro models such as GPS, LED strips and DJI digital air unit are removed to further reduce body size and cost, with clean wiring and no redundant function waste.
4. User-Friendly Open-Source Firmware for Entry-Level Pilots
Fully compatible with the mainstream Betaflight open-source flight controller firmware, it features a clear and easy-to-understand parameter interface with low tuning threshold. It supports custom basic flight parameter settings, allowing beginner pilots to get started with debugging quickly, ideal for entry-level practice drones and DIY micro RC projects.
5. Ultra-Compact Design for Wide Mini Model Compatibility
It adopts an ultra-small compact design with extremely light body weight, adding no extra payload to micro aircraft. The standard micro mounting holes perfectly fit various small-size RC models such as 2-3 inch toothpick drones, indoor ducted drones, mini fixed-wing planes and micro gliders, making it the top cost-effective choice for micro FPV builds.
