Now we could be talking about two different things but what I thought you were talking about was the active braking on the Takyon SOC which the documentation goes into some detail about and says “Active Braking: The motor actively provides a reverse torque when decelerating, recovering some of the rotational energy. Normal braking mainly relies on air resistance.”

Now I’ve never flown a drone with a Takyon SOC but I took that to mean that, say the AC is pitched forward at -15 degrees with the thrust angle pointed directly down through the body of the drone just like normal. But when it wants to brake it reverses the props momentarily to slow it’s forward motion with the thrust angle pointing directly up through the craft and then levels the craft and reverses the props again to come back to the normal direction. Maybe it still needs to reverse tilt just less? If you look at the props they are a lot like the
M1 OG props which are more like blades. The M2 props with the winglet are clearly only designed to rotate in one direction.
But yea I guess that’s kinda what I had in mind actually but it doesn’t sound like the battery actually gets recharged it just uses less energy to brake. With a Tesla you could potentially charge an almost dead Tesla battery by rolling it down a large enough hill
