[NSRCA-discussion] snaps

[Troy Newman]

Yes!  I agree with this philosophy completely. Different models will
"look" slightly differently in the autorotation. 

The geometry of the line must be preserved.

While this is a lot of fun... at the most recent Worlds the
pilots/judges were told... If it's not an axial roll, and it's not a
barrel roll, it must be a snap roll. Take it for what it's worth.

			Given the abundance of snap maneuvers(7
maneuvers, 9 snaps) in the F-11 pattern, I feel compelled to give the
exact description via the F3A rulebook:

			 

			A snap-roll is a rapid autorotative roll where
the model aircraft is in a stalled attitude, with a continuous high
angle of attack.

			 

			Snap rolls have the same judging criteria as
axial rolls as far as start and stop of the rotation, and constant
flight path through the manoeuvre is concerned.

			 

			At the start of a snap-roll, the fuselage
attitude must show a definite break and separation from the flight path,
before the rotation is started, since the model aircraft is supposed to
be I a stalled condition throughout the maneuver.  If the stall/break
does not occur and the model aircraft barrel-rolls around, the manoeuvre
must be severely downgraded(more than 5 points).  Similarly, axial rolls
disguised as snap-rolls must be severely downgraded(more than 5 points)

			 

			Snap-rolls can be flown both positive and
negative, and the same criteria apply.  The attitude(positive or
negative) is at the competitors discretion.  If the model aircraft
returns to an unstalled condition during the snap-roll, the manoeuvre is
severely downgraded using the 1 point/15 degree rule.
