A-6 National rules

For the past three weeks, a group of 8 modelers joined together in a
dedicated Yahoo group to discuss A6 rules. This was announced on
Indoor_Construction Yahoo Group and everyone interested was invited.

There are at least 4 sets of A-6 rules out there, which at times
compete with each other, sometimes confusing those who want to build
A6, and they have to ask, "Whose rules, and where are they?" It was
the hope of the group to decide what rule set is already the most
common and accepted, and to clarify any obvious problems. The group
contained a few of the more successful A6 flyers, who knew the
problems in the context of local and national contests. We present
here the results, which will also be posted in Files section of
Indoor_Construction, called "A-6 National Rules." It is our hope
that this effort will be accepted by general acclamation.
Obviously, 8 modelers would not have the authority to change
anything. On the other hand, it appears no real A-6 authority even
exists, except individual CDs or perhaps clubs. Therefore, no rule
below changes anything the about model's description, at least as
flown at USIC and Midwest Champs. It is hoped that everyone
concerned will accept the one "new" thing, and that is for
contestant to provide the CD with a drawing of wing area
calculations, purely for the convenience and accuracy of model
processing at contests. These rules will also be archived on at
least two other websites, which fortunately also had moderator's
representation within the A6 group: IndoorNews.com and Small Flying
Arts. The group was Jerry Combs, Gary Hodson, Chris Borland, Andy
Ondrej, Jeff Hood, Tom Sova, and Mark Bennett.
Sincerely,
A6 Rules Group.
