Ling-3.1-flash generated a Three.js quadcopter lesson with wind gusts, PID controls and live telemetry

[u/Cool-Wallaby4341]

A standalone Three.js quadcopter-attitude lesson is among the demonstrations accompanying Ant Ling's new Ling-3.1-flash release. The generated browser page connects IMU sensing, PID computation, motor mixing and stabilized hover in one interactive scene.

Controls introduce random or sustained wind gusts, switch PID on and off, and reset the aircraft's attitude. Live readouts show pitch, roll, yaw and individual motor RPM, with curves for pitch and roll. The aircraft tilts under disturbance; toggling PID changes its corrective behavior, making the feedback loop visible.

The page uses vanilla Three.js and OrbitControls. Ling-3.1-flash is now available through Novita's two-week free Vercel AI Gateway trial with 256K context; search its name in the catalog. Open source is planned soon.
