  Let me rephrase: why would companies consider battery life a limit when liquid fuel is a viable way forward for range, time-aloft or size?

    Repeating my post above: Given the line of sight limitation for drones, gas power does not add much value. Batteries are usually sufficient to map/photograph the area within range of the operator. Given this legal limitation, it is often more economical to hire a small plane like a Cessna with an avionics package and a 400 mi range.
