There has been "grumbling" of late, and even if this grumbling is way off base, it seems to me that it might be easily corrected? The grumbling comes from flyers who feel that the judge(s) are "too close" to flyers or too familiar with the airplanes themselves to be really objective.
This year I wandered over to the rc pylon racing area and spoke with several there. I believe that appearance plays a role in their grid position, or some such? Their aeroplanes are generally exquisitly finished in terms of smoothness and recognizability.
These guys would be happy to wander over and do appearance judging! They will carry no "baggage" and any implied "favoritism".
Using informed outside judges will not put an end to an individual feeling that he got "scr*wed", but would certainly lay any suggestion that the judge(s) were playing to their friends.
See Ya
