Yes. The add-on is GPL 3.0 or later; your renders and animations are yours.

Blender 5.0 or newer.

Both. Flying is done in the viewport; the result is keyframes, so render with any engine.

Pick any camera in Quad > Camera to fly it. The built-in 5-inch drone model can be hidden, or parent your own model to the FP Drone object.

Yes, while recording the timeline runs with you, so moving cars or doors are where you see them.

Yes. It collides with visible meshes, a chosen collection or an invisible floor, including instanced and Geometry Nodes geometry. On a crash it can bounce, reset or pause.

Yes, a clean prop sound plays while you fly. Nothing is added to your scene.

Hold Rewind (Q) to run time back a few seconds and try the gap again, or turn on slow motion: the simulation runs slower, the recording plays back at real speed.

Yes. Each flight is saved as normal keyframes in its own take. You can retake from any frame (a short pre-roll, then you take over), smooth a take, or bake a stabilized camera with a level horizon.

Rates use the Betaflight formulas (Actual, Betaflight, KISS, Quick). Paste your Betaflight CLI diff and your rates, expo and throttle curve are imported. Pick one of 13 drone presets (freestyle, race, toothpick, whoop, cinewhoops, long range, cinelifter, beginner trainer); each comes with its own rates, throttle curve and flight time. Or tune weight, thrust, drag and response yourself.

Yes. Cine mode makes it easy: arrows set speed, let go to brake and hover, W/S climb and descend. Every key can be changed.

No. Controllers are read directly through Windows, Linux or macOS. There is no "install dependencies" step.
