Dale,
Phil Ploof and I have changed airplanes into Gyros numerous
times and it is a simple way out.
It appears your pylon should work, but like said be sure to have
an angle of attack and a nose down hang angle.
Rotor blade area should be enough to get a disc loading of
under 6 oz. per square foot. ( disc area divided by flying weight)
Good luck, have fun!
