The usable energy density of fossil fuel is hard to beat, especially in a weight-constrained application like a drone. I'm surprised more of these haven't hit the market yet. The refueling advantage is substantial in a fleet application, too.

Weight-constrained and energy-hungry. Fixed wing drones can stay up for much longer.

Have both, a quadplane.. (or triplane in the below case).

VTOL (Vertical Take Off & Landing) plus the economy of fixed wing flight. In the case below, flown automatically by ArduPilot. https://youtu.be/hDG-KlYyYDU?t=65
