May not be exactly the same, but I don't believe there's an appreciable drop on a tiltrotor like the V-22.

There isn't - the V-22 rotors tilt continuously from vertical to horizontal rather slowly as it builds up enough speed to transition to forward flight. Same thing with Quantum's VTOL UAVs.

And since the Heaviside has many pairs of small rotors, it has another option which is to switch the rotors gradually pair by pair, but switching each pair quickly.

I thought about that (and watched a few examples) but these would have a much less powerful motor, so I was curious how it handles it.
