Fidelity X

Flight, Reimagined

Real-time Kernel · Precision Filtering · Progressive Protection

Between You and the Sky, Just a thought away.

Not optimization, but built from scratch—crafted on a real-time operating system, with a carefully tuned signal chain ensuring both sharp response and silky feel, and progressive safety mechanisms keeping every landing under control.

Performance by Architecture

Instant Response

Parallel architecture, independent tasks—from fingertip to propeller, microsecond delivery, seamlessly

Built from Scratch

Every line of code, born for flight—no porting, no compromise, only purity

Progressive Protection

Multi-stage safety mechanisms, from signal recovery to safe landing, every stage has a plan

Precision Filtering

Carefully tuned signal processing chain, where sharp response and silky feel are no longer a trade-off

Experience from Details

Precision Modeling

Based on rigid body dynamics, every response of the aircraft behaves exactly as it should

One-Click Calibration

Sensor self-calibration, just rest for a moment—let the firmware handle the complex tasks

Intuitive Configuration

Clean interface, clear logic—understand at a glance, master immediately

Lossless Recording

Newly developed lossless blackbox logging, your every action precisely recorded and fully restored
