so ive had my mini 3 pro for about 3 months now and outdoors it flies absolutely fine, gps locks fast and it holds position like a rock. but whenever i try to fly it inside my garage just to practice a bit or get a quick shot of something, it just slowly drifts and i have to keep correcting it. i thought the downward vision positioning sensors were supposed to handle this? ive got the sensitivity set to normal and vps is definitely enabled in the settings, i checked like three times. the floor in my garage is just concrete with some oil stains and a workbench, nothing crazy. is it maybe the lighting? i have one of those single hanging bulbs and its not super bright. or is the mini 3 just not that good indoors compared to like a mavic or something

lighting is almost definitely your issue. the downward sensors on the mini 3 need decent contrast and texture to lock onto and a dimly lit concrete floor is basically a worst case scenario for vps. try adding a lamp or two pointed at the floor and see if that helps. also oil stains are actually fine, its more about the light levels than the surface pattern. i flew mine in a warehouse once with similar conditions and it was a mess until someone turned on the overhead floods, then it was solid.

yeah indoors is just kinda rough on these lighter drones in general, the slightest air movement from like a fan or even a heating vent can push it around too. i dont think any drone in this price range is going to be super stable indoors unless conditions are perfect tbh
