In a previouis post I discussed the physics of hovering drones and helicopters. My interest in the physics of propellers was reignited by video discussing the possibility of a wind-powered vehicle to move faster than the wind (in the downwind direction).

After playing a bit with a DJI Mavic Air drone I started to wonder what are the differences between the physics of drones and helicopters. One particular question is which one would be better to hover with given weight. Also how long can a drone and/or helicopter fly (hover)?

Some time ago I got access to a 3D printer. After learning to use the Blender software I put together several decorative 3D models. Some are even printed.
