  Don,
  What version of the A-6 rules did you submit?
   Bill,
  The topic of allowing plastic coverings has been discussed numerous times on various forums. While there may be some advantges to plastic, I remain against allowing it, simply because it is preceived by many newcomers to be more difficult than tissue covering. And A-6 is an entry level duration event. Also, A-6 is one of the more popular events at local indoor events and at the USIC. I suggest that it is working well as it is & should be left that way.
  Gary

  I have proposed at a couple of times that the "official" rules of this unofficial event be changed to allow Mylar. The original idea of A-6 was to have an event that was an "easy" event and everyone knew that working with plastic film was much more difficult than paper. I think if you will ask anyone who flies A-6 about whether paper covering makes the event "easier" you will get the choice of "no" or "no" with some modifiers in front of it.

  If there is a chance that A-6 will get into the AMA rule book then I think that we should make sure that the prohibition of plastic covering dies with the event's unofficial status.

  Don, would you consider amending your proposal to eliminate rule #9? I will support your proposal in either case.

    Since Ultra Film doesn’t change trim with changes in relative humidity as condenser paper does and since this novice finds Ultra Film easier to work with than condenser paper, is their any chance of getting the condenser paper requirement removed from the A-6 rules when the indoor board votes?

    On a related subject I have submitted A-6 as an official AMA event for 2011. Hopefully the indoor board will vote to allow it in.

    Sergio,
    Thanks for the very clear explaination. It all makes sense & I am beginning to think experimenting with turbulators in this application may be a waste of time.
    The A6 rules require a minimum 1/16" square leading & trailing edge. I have tried rotating the square leading edge 45 degrees from that shown in your diagram. This gives a more streamlined leading edge but I cannot say if it is better or worse. I guess I could also build a tapered leading edge as long as it was large enough to contain a 1/16" square.
