Its always been that way, show up at the field with something different and somebody's going to poo poo it. The worst I ever had to deal with that mentality is when I started flying IMAC. If I had a dollar for every time I heard " You guys with your big airplanes" Then followed by the accusation that we are too loud, flying too high, flying to far out, getting in the way, etc. Race planes were never much of an issue as most of the clubs I have be a member have had racing series.
