Ok just to clarify my first statement.

It was a negative snap and the elevator was down and the rudder was applied at the same direction as the ailerons --> hence wrong direction. I do fly unlimited and had attended judging seminars in the past so I was pretty confident my zeroing of this snap was a good thing to do but being a guy that always listens to others that have more experience than me, especially this guy that used fly full scale competition which we are supposed to try to duplicate, I had to ask here... In fact we don't really try to duplicate full scale as we make snaps that don't look like snaps, but that's another story...

I was feeling bad as I zeroed this guy the Humpty bump in advanced for all sequences I judged and this happens to be the critical maneuver with the biggest K factor. That put him back by at least 3 positions in the rankings of that competition.

BTW, last weekend I tried to snap without ailerons at all. Looked much more like a full scale snap and while I was thinking it made a much too deep snap that almost stopped the plane, my friend told me it was almost deep enough for a full scale snap... That rendred my plane useless for the hammer head in unlimited where I have to make 1 1/2 neg snap on the upline; not enough power.

Thanks for your help guys!
