[Ed Miller]

Concerning the Master schedule 1/2 loop with full roll out.  Is a slow roll 
acceptable on the full roll out or must it be a fast axial roll ??

> 1. Since the maneuver is defined as a stall maneuver (initiated by a rapid
> stall of the wing induced by a change in pitch attitude), the nose of the
> fuselage should show a definite break from the flight path in the 
> direction
> of the snap (positive or negative) while the track closely maintains the
> flight path. The track visualized as the path of the Center of Gravity 
> (CG)
> should ideally follow the geometric flight path of the maneuver while the
> nose and tail autorotate through opposite helical arcs around the flight
> path. A snap  that does not show a break and stall to initiate the snap, 
> but
> does enter a stalled attitude during the maneuver is severely downgraded.
>
> So
> * lack of a definite break of the nose is not a zero but severe downgrade
> * track of CG should ideally follow the geometry of the maneuver for max
> points
> Other Points:
> * Barrel roll or axial roll is a zero
> * Speed of snap is not a judging criteria
> * Airspeed may decrease in the snap with no downgrade
> * If model is roll to a finish the downgrade is applied using 1 pt per 15
> degree rule.

>> Good stuff, Don.  These are very helpful for learning a schedule that
>> you don't fly.
>>
>> I have a few questions about judging Masters that I recommend should be
>> answered on the presentation.
>>
>> 404-2:  Does the stall turn itself have to rotate in the upwind 
>> direction?
>> 404-7:  There seems to be an option here, but 2of2 has the same name as
>> 1of2, though the Arrestis are different.
>> 404-12:  What is the rule book definition of 'slow?'
>> 404-18:  The rulebook definition/description of a snap?
