Re: A6 to become new AMA event ?

Now I have a problem. I emailed Don about the 50% stab and he said he would not remove that rule. The USIC rules and the "national rules" do not have this stab area restriction. My personal A-6 design has a 24 si stab. Changing to a 15 si stab would probably mean designing a new model.

To confuse matters more I looked at all of the A-6 designs on Jeff Hood's website and found that all of the stabs were under 15 si.

Am I the only A-6 flyer that is not in line with this non-existent rule? If this rule has been used in the past why was it dropped for USIC and the "national rules"?

  A6 flyers,

  The new A6 rule set reportedly submitted to AMA by Don DeLoach contains at least two substantive differences with the "2006 A6 Committee" rules (available in InCo Files section.) The DDL new rules copied here below.

  Notice the prop rule (#8) where the specification "wood" has been deleted. This would allow use of foam for prop blades or whatever else. To back this up, in his rule #10, the general high tech material prohibition and specific foam prohibition has been deleted, compared with 2006 A6 Committee rule set.

  Also notice rule #2--a new thing for A6--where tail area is limited to 50% Some of you would need new stab.

  For all I know, many affected A6 flyers have been contacted by DDL for collaboration, input, feedback about this new rule set. IF SO, please enjoy your new A6. (PS, it takes two rounds of AMA voting, so this won't happen overnight.)
  JMO,
