Back when we flew multiple Cessna’s at my skydiving school instead of the big Twin Otter we would routinely fly formation loads whenever we wanted to build formations with more than four skydivers. One of the things I really hammered into my pilots was how to stay out of the lead aircraft’s wake turbulence on takeoff. I caught just a little bit once on takeoff and it took a big control imput to keep from being sucked in further with potentially disastrous consequences. I can’t imagine the wake those two huge rotors/propellers put out. Probably want to stay clear huh?
