Highly Reliable Components

Reliability is always the foremost concern for components of M2 flight controllers from their designs to their type selection. All components of these flight controllers are industrial and strictly tested to guarantee safe flight of unmanned aerial vehicles.

Distributed Design

M2 flight controllers have distributed designs for ensuring hardware and software modularization while increasing system reliability. The M2 flight controller in the basic version has 6 CPUs, which have their separate functions.

Intelligent Avionics System

Topxgun’s ground stations can be applied in PC, iPad and Android devices through 900MHz wireless data transceivers. These devices can be selected according to actual demands, in order to exert remote control over aircrafts.

Powerful Product Performances

In terms of designs, great importance is attached to product performances of M2 flight controllers, which adopt brand new multi-sensor fusion algorithms, attitudes and position control algorithms. Being helpful for high-precision centimeter-level positioning and long-range data transmission, they can greatly improve performances of unmanned aerial vehicles.

High-performance IMU

M2 flight controllers are equipped with automotive-grade gyroscopes and accelerators. Compared with the last-generation products, the precision of the gyroscopes is 20 times higher and the seismic capacity is 10 times higher. The accelerators, with nitrogen-based damp-proof anti-vibration designs, show stronger damping capacity and higher precision. In addition, IMUs of M2 flight controllers are calibrated within the full range of temperature. In combination with the brand new sensor fusion algorithms, the precision of attitude measurements is within 0.5°.

Open Platforms and Applicability to Secondary Development

M2 flight controllers have spare special APIs (Application Programming Interfaces) and provide SDK of Android/IOS. Combined with OCP, they are applicable to various supporting products of unmanned aerial vehicles and secondary development of airborne software.
