[NSRCA-discussion] Suggested New Snap Roll (Break Roll) Description

[Vicente "Vince" Bortone]

This is new version.  



SUGGESTED NEW DESCRIPTION (CHANGE FROM SNAP ROLL TO BREAK ROLL): 



Break Roll:  Break roll is a simultaneous, rapid auto-rotation in the pitch, yaw and roll axes. The following criteria apply: 



1 . Barrel and or axial roll shall be downgraded 10 points.  The lack of helical arc (or definitive tail coning) is indicative of not performing a break roll and is scored zero.   



2. The track visualized as the path of the Center of Gravity (CG) should closely follow the geometric flight path of the maneuver while the nose and tail auto rotate through opposite helical arcs around the flight path.  1 point per 15 degree rule is used to downgrade any deviation. 



3. If the auto-rotation is visible as prescribed but the model rolls or barrel rolls to complete the maneuver, it would be downgraded using the 1 point per 15 degree rule. 



4.   Break rolls have the same judging criteria as axial rolls as far as start and stop of the rotation.

Search for "brake" and replace with "break."  :o)
