I had an amphibious drone.....once.
Wasn’t supposed to be, but those little stick thingies are hard to use.
Watched a guy try out his two really nice model radio controlled amphibious airplanes from a lake during my Saturday morning run near a lake a number of years ago. I stopped and watched from a distance for a while. He took one out on his canoe and tried to have it take off from the water. Crashed it. Retrieved it and got the second one. Took it out on the lake. Same story. It was time to finish my run.
Didja get what ya paid for?
