Im no IMAC guru but i must say most snaps I see are so far from the full scale equivalent in that they happen so fast I wonder how you guys that do the judging have any idea at all what inputs where put in and what actually happened during the manouvere. I personally snap with minimal possible inputs, and i release the elevator almost immediately for 2 reasons 1) otherwise my plane overrotates too much, 2) i just think it looks alot nicer and you can actually see the motions of the plane through the snap alot easier as it occurs a little more slowly. On the guy swho used same side rudder for a 'shoulder snap', actually although this manouvere isnt really a snap at all i think it can look very graceful and is a nice manouvere to execute. Though obviously out of the schedule!
