Props to the props
For max flight time you want to run the largest props possible. Astro uses 21 inch props on a drone body that’s only 14 inches square.
96% of our total area is props!
So why doesn’t every drone do this?
It’s hard!
As you increase prop size it becomes more and more difficult to accelerate and decelerate the prop. Ever notice how FPV drones use absurdly small props? They trade prop size / flight time for control bandwidth.
On Astro we spent years developing motor drive HW and control algorithms that allow us to have huge, slow-spinning props with incredible stability. This allows Astro long flight times, incredible precision, and super low noise footprint.
