THOR Transformer Drone Hovers and Cruises With No Compromises

Wings are great for crusing over long distances and carrying heavy loads, but they aren't that great if your aircraft needs vertical agility. Rotors, on the other hand, are great for vertical agility, but they aren't that great for long distances and heavy loads. Any aircraft that wants to fly efficiently can be designed for cruising or hovering, but not both. Lots and lots of people have tried to figure out a way of making some sort of compromise work. Mostly, this involves stapling as many vertical rotors as you have a budget for to a fixed-wing aircraft and just calling it a day: When you want to go up or down, you use the vertical rotors, and the rest of the time, you use whatever other rotors you can afford to have mounted horizontally.
