[SPAM] Re: Displacement during snap rolls (was Why is it so quiet?)

[Fletcher, Richard]

I am late to this thread but speaking from an SA perspective, it is not
possible to do a true snap and not have it displace off of the line, at
least not during an upline snap. If a plane was able to not displace from
the line, I would think the pilot reversed the rudder and elevator control
inputs at about 1/4 - 1/2 roll from the snap's completion. In which case you
would see the autorotation stop and the plane would appear to 'aileron roll'
to completion of the snap. Which in SA would be 1 point per 10 degrees of
rotation off. Don't ask me how I know that.  :)


Thanks, Rich

That means my interpretation of correct presentation of a snap can be that
offset is perfectly acceptable.  If you're in the chair NEXT to me, judging
the same guy, and you hammer him for it, does that mean BOTH of us are
correct?
