This is kind of the 'sky is falling' kind of thing I was talking about...
Nobody I fly with has a turbine or a plane over 15lbs, let alone 55lbs.
Then by that we should presume that those that do should feel it is OK for them to lose their ability to enjoy their models. A 400 foot altitude limit would end RC soaring (we launch higher than that), pattern, IMAC. 100 mph limit ends pylon racing and turbine. But hey, nobody you know does those things so why worry?
Perhaps looking outside just your little neck of the woods might help you to understand the threat we are up against.
