The lighter the airplane the more turbulence will bounce you around......You ought to see my field.....wind out of the southwest.....there is a ditch and a line of trees aways from the end of the runway...as you cross that ditch there is a rolling turblence of air that will rock and roll ya until 20 or so feet form the threshold. I am flying an 18 lb airplane. It will rock and roll 40 per centers
