Seems unlikely to be a quadcopter given the 100mph airspeed it was capable of

Nonsense - you can build a quad capable of that speed for ~$500.

It won’t have a flight time of more than a few minutes, though. For that, you’d need a fixed wing, or a non-lipo power source (like, say, hydrogen)

Mavic FPV goes to 100mph in Manual mode.
