[NSRCA-discussion] Snaps

[Del R]

They do fabulous inverted spins too / and it don't take much to make them go flat..... !!!

      We accommodate / adapt to rules in many ways. Interesting review of full scale. Wings make a difference. I got a lot happier as I transitioned from a 2:1, 12% wing to a 2 1/2 :1, 14%.

      Hard to believe no discussion on a snap thread.that's a first. 



      I watched the French Connection video with interest since they were very much at the top of the airshow list at around the time I was into full-scale aerobatics. 

      We always figured that FC was able to pull off the "snap-on-the-deck" stunt because of the CAP-10's airfoil, which was closer to a glider airfoil than to an acro airfoil. Hence the deep wallow before the autorotation that results in the displacement of the flight path.to their advantage in this case. They used to do the two-plane formation snap on take-off, which always impressed me to no end.

      If you watch Patty Wagstaff do a snap, with a thin, fully-symetrical airfoil and added full-span stall strips, her snaps become virtually identical to the FAI "twinkle snap". A Pitts S-1 is somewhere in between. The Citabria, needing full "con" ailerons, will pause for a split second, then autorotate in a flash with surprisingly little displacement. So 10 different planes will all autorotate differently, some imperceptibly. Accordingly, many full-scale pilots snap with ailerons "pro" instead or with the traditional ailerons "con". Heck, most full-scale competitors get 10's on spins and they are literally flying/slipping the plane down the spin.never having stalled at all. 



      So for pattern, if it slows down for a micro-second, and the tail describes a cone, I call it good, even though I still can't do it that well myself...

      well since masters is know taking on traditional FAI maneuvers" rollers and such".. the twinkle snap will become the standard in AMA ...I will be doing one in the upline snap from now on...

      Well Don, that really didn't fire up a lot of enthusiastic discussion. I guess after Nats it's don't ask don't tell.

        I just watched CPLR and Mayer doing snaps on video. The entire video is their snaps.  If you are interested, here's the link http://www.rcgroups.com/forums/showthread.php?t=1443881&page=2

        about half way down the page.  A good exercise is to watch both videos and record your thoughts. Then get a thin piece of straight wire and overlay the track of the models when they snap. See if your views change. The ability to replay a short segment is a help.



        Especially watch the snaps at 1:40 for CPLR and about 2:00 for Mayer. What do you think? Note the post just after Mayer's video.
