Ty,
Around here, there is not BOM or appearance points in the profile event. At a typical contest, there will be some 10-20 entrants. Of 20 planes, 13 or 14 will be ARFs. Virtually all Pat Johnston designed Brodak P-40s with a few ARF Flight Streaks or Tutors or whatever thrown in. It's a lot of fun with usually a few crashes. No one cares too much, but as a judge, it's gets old seeing the same plane, flight after flight. Oh well, the pilots have fun.
