No restriction on stab area is weird. Typically stab area over 50% of wing counted as wing area.
A tandem would be limited to 20 si by old rules going back to the 1930's.

No biggie, just weird. H

      I couldn't find the A- 6 rules in the set of indoor rules on the AMA's web site. I know I am in the right place because the rules I read cover F1D, F1M, Penny Plane, EZ B, etc. Maybe I overlooked them in this set of rules?




Where can I find the AMA rules for the A - 6 class?



Thanks
