I fly at a feild abouty 5-6 miles away from anyone and I use the electronic game ear i use to hunt with, yes I am an avid hunter, dont hate me!, but I like the loud sound of a stung out weed eater, but i do take everyone around into concideation, but normally it just me and my buddy matt, we wear ear plugs to do straight pipe on anything, especially the honda, thats a maen straight header enging, 499fhp, 542 N2O horsepower.
