Wowbagger "common sense" wont do it. Manners ,applied to the rules, is the answer I think. Human nature being what it is, one man`s common sense isnt always the other guys. Bad habits and a "cushy-ness" ,familiarity with regulars at the strip all gets upset when a newcomer arrives to fly or spectate. When the rules are pointed out it sometimes "spoils the fun" and perhaps loss of a new flier to the club. They probably go and fly on their own causing more problems. BMFA have thousands of man-hour-flights experience and hence "the rules" (SAA in Scotland). I dispair at the number of cheap electric "toy" R/C flying models that bit the dust just after Christmas and birthdays, all on our 200 mph gas turbine frequencies. Hope this doesnt get the forum bogged down. We are all guilty, when we think nobody is looking we all take the odd risk.
