[NSRCA-discussion] Avalanche - Positive or Negative Snap?

It takes more playing with the setup to make it really snap nicely positive
to where it doesn't drop the nose too much, but when they are done correctly
positive, I think the presentation is much nicer.  I think geometry is much
easier to maintain with a positive snap.

I again stand corrected.  My thought was that the snap should be to the 
outside of the loop to control the amount of drop that the model will 
encounter, being in the stalled position.  I don't recall judging anyone 
that did a positive snap, but I certainly see Arch's point.

This is why Archie flies the way he does, and I fly the way I do <BG>
