Flight Control System
THE BRAIN OF THE DRONE
The Flight Control System is the brain of a drone.
It constantly reads data from sensors such as the IMU, GNSS, barometer, and optical flow, then calculates how fast each motor should spin to keep the drone stable.
Without the flight control system, a drone cannot hover, fly straight, or return home safely.
Imaging System
THE EYES OF THE DRONE
The Imaging System turns flight into storytelling.
It includes the camera sensor, lens and FOV, stabilization (EIS or gimbal), image processing (ISP), and the final output choices like resolution and frame rate.
Power System
ENERGY BEHIND EVERY FLIGHT
The Power System is more than “battery capacity”.
It includes battery safety, power monitoring, charging,
ESC power demands, and clean power delivery through wiring, connectors, and distribution paths.
Propulsion & Airframe System
THE FORCE BEHIND FLIGHT
This system converts electricity into thrust and keeps the drone physically stable. Motors, propellers, frame arms, and landing gear work together to create lift, handle stress, and survive real-world takeoffs and landings.
Drone Wireless Communication System
THE CONNECTION TO YOUR DRONE
Wireless links are the invisible bridge between your hands and the drone. Control commands go up, video and status come down, and telemetry keeps safety features working in real time.
