Nope... never did any of that stuff. Everyone I've worked with down here has though. That little airplane is a crop duster with a 540cu inch flat-6 engine, roughly 280hp. It screams, and the airplane crawls along.
Anyway... they fly along ok, but if it rains they'll get really heavy, especially the big billboards like the Geico one. I guess they can get heavy enough that it becomes dangerous and they'll cut it loose.
