Have you actually seen a helicopter? Know anything more than they are rotary wing aircraft? Do you know about rotor wash or range, especially when carrying a load? Do you know how difficult flying with a hanging load it is and how much stress it puts on the airframe? Did you know airframes can bend since the entire aircraft is supported by its rotor head while the airframe itself is actually carrying the weight?

Your robo horse thing also ignores the energy usage of an animal vs robot. The animal has a distinct advantage.

Again, you have no idea what you’re talking about. Hopefully you’re not an engineer by trade, as you’re failing at pros and cons here.
