major update

Flight model — major rework

  • Physically correct airframe inertia. The quad now uses the real measured moments of inertia of a 5" 6S build instead of values derived from its collision shape, which were roughly 25× too light. This is the biggest change in the update and it affects everything about how the aircraft rotates.

  • Eliminated a persistent high-frequency oscillation. A 110–140 Hz resonance was present in every previous build — it's what made the motors sound and feel "dirty" during low-throttle rotations, free-falls and powerloop exits. Measured body-rate noise dropped from 19–85 dps to 1.6 dps.

  • Inverted flight fixed. The quad now falls correctly when inverted instead of skipping and hanging. Powerloops and inverted descents behave properly.

  • Free-fall momentum. Throwing the quad now carries speed and glides the way a real one does, instead of braking short.

  • Landing fixed. The quad settles on the ground instead of bouncing off it.

  • Yaw authority corrected.

  • Descent feel — cleaned up grit during fast vertical descents.

Vibration model

  • Rebuilt as three separate sources — motor, propeller and frame — each calibrated against real Betaflight blackbox logs rather than a single blended noise knob.

  • Frame resonance reworked, and the noise simulation now runs at a higher internal rate for accuracy at high RPM.

Audio

  • Night ambience now plays. The nighttime coquí forest bed was being silently stripped from packaged builds — it worked in development and was missing in the shipped game. Daytime ambience was affected by the same bug.

Interface

  • Tuning menu sidebar now fits a 1080p screen — buttons were being cut off at the top and bottom.

  • Controller enumeration and device selection now work in the shipped build.
