After several accidents, and loss of valuable cargo because the tail on the original hopper had massive problems in the mechanical area, the company making the hopper fired the designer and hired another. This is what he came up with. A fat tail with no twisting action to go wrong. And more room for cargo. Some redesigned arms for the container as well. Not quite the speeddemon, but nice and reliable. The company were rather pleased with the designer, and lett him ceep the job for other projects.
Well, its in the same family as the hopper as you can see.
