    Manual pre-rotator

    Good evening fellow rotorheads, Than gentleman's name was Rufas Howard. He was a longtime member of P.R.A. chapter 25, the Badger Mini Choppers. Tom Milton may know him. I believe his pre rotator was featured in an issue of Rotorcraft magizine in the early or mid 1980ies.

    When floks ask what is it like to fly. What do you tell him?

    I tell people " If you've ever imagined what its like to fly on Harry Potters broomstick, that's what its like !! My ultralight friends would interject, " Its like flying a jet powered rock, when the engines running, its like a jet...when the engine quits, its like a rock" !!
