Well this week seems to be all about the toroidal balde, or rather prop which we can possibly use on our drones. Did a quick test, in the cold, to see how they would work! First impressions, not too bad for a 3D printed part. A company like@Gemfanhobby needs to take on this challenge and see what they can come up with.
