RE: What does the average sportsman competitor fly?
I won Novice in '98. Billy Borland won a District V (i think) advanced contest with his runaround in around '02. His flew with a YS91, mine flew with the OS. I actualy built a second runaround last year with a saito 100 that came out under 7 lbs. I never flew it in a contest, but I would have been just as competitive with it cause it just felt right to fly. I flew my first runaround for 4 years as my only plane. Currently flying advanced with a Jupiter (still not quite 2M). I started this season with a Focus, which is a noticeably better flying plane than the Jupiter, especially for the 45 down snap and the avalanch, but it met with hard times. The ruanround is a very neutral, good flying plane. Some guy out in Utah (Some Dudes Hobby shop) is still kitting them.
I think your underestimating piloting ability vs plane a little. Didn't Fortino win the Nats a couple of years ago flying a 60 boxer? I'd say that's pretty competitive.
