No problem Mike. I just repeated what I have seen and judged at IMAC contests for the past 5 years. I didn't mean anything derogotory (sp?).

ORIGINAL: v-snap

How far the nose breaks has nothing to do with it being a snap or not. In other words the nose just has to break the plane for it to be considered, not by any minimum amount of degrees.
I completely agree.
That full scale pitch varies according to aircraft also. You may not see a huge break in a full scale snap either, it depends on the entry method. I have seen some experimental's with very little nose break when they attempt the use of ailerons in the snap (like models). Hense the argument of was it really a snap or a bump of elevator with a extreme roll rate..
This is where the reynolds number comes in to play. The point I was trying to make is that we can't imitate a large pitch like the full scale planes and have our snaps exit remotely straight. The full scale pilots that use a very small pitch and the ones that you probably are talking about that were being questioned years back, we can try and imitate and they're what we have been doing, but they are still going to look slightly different regardless since the full scale aircrafts cg is going to remain on its line with a little or large pitch before the snap. If we use anything more that a very little pitch, then our cg is going to veer off of the line before starting the snap.
These same questions came up in the full scale area as well (at least when I was a little involved in the 90's).
I am not trolling here either, I like these discussions. And beleive it or not (even though I will never admit it) sometimes I am wrong and need to be corrected.. It has been a few years since I have gotten to discuss the actual maneuvers, and I can't wait to get my first of many zeros so I can moan and groan.

I'm not in disagreement with you as to what is or isn't considered a snap, I was just trying to clarify to the people following the thread what the largest difference is in how the full scale and our scale planes can successfully snap an aircraft and keep the cg on a straight line from entry to exit since that is what we need to accomplish in order to score well.
