    Approximate whoop physics — not a thrust-stand log. Feeds mass, inertia, thrust, spool, and battery sag. Betaflight CLI paste still sets rates/filters only.

    Values are approximate.

    Physics

    Betaflight 3D: throttle center is zero, below center reverses the props. Flown in Acro. 3D runs are not counted on boards or as ghosts.

    Whoop feel — duct bounce, wash, cushion, drafts. Strength follows Your build (frame / KV / AUW). Defaults are 65mm indoor.
