[NSRCA-discussion] Masters 2009: Two 2/2 reversed

[rcmaster199 at aol.com]

Reversal is immediate. Point rolls require hesitation

Immediate reversal means as soon as model's wing reach horizontal, 
model needs to start the opposite roll. There are situations in 
maneuvers where opposite rolling elements are present (Reverse Point 
Roll, Reverse Knife Edge,etc., for example) where reversal MUST NOT 
happen immediately because a hesitation must be flown of some duration.

But in TWO, 2/2 Rolls Opposite, the description requires 2 individual 
and complete 2/2 rolls to be done, in opposite directions. This follows 
established precedent (first done in F3A assymetric rolling maneuvers) 
where two different rolls were required in opposite directions.  I am 
pretty sure F3A folks remember the 1 1/2 Snap. 4/8 Roll opposite they 
flew about 6 or 7 years ago. It was the first such maneuver introduced 
into Pattern

Look a little further down:

 

Two of Two Point Rolls Reversed – From level upright or inverted flight,
model performs one-half (1/2) roll to level inverted/upright flight, 
hesitates,
performs another one-half (1/2) roll in the same direction to level 
upright/inverted
flight. Immediately the model
performs one-half (1/2) roll to level inverted/upright fli
ght in the 
opposite
direction to the 1st two half rolls, hesitates, performs
another one-half (1/2) roll in the same direction to level 
upright/inverted
flight.

Masters 2009: Two 2/2 reversed

 





  I checked the RCA and I didn't see anything for Two
  (2) , 2/2 Reversed. I used the NSRCA link to the RCA


  2009-2010 RCA-32: "

  Two
   (2), Two of Four (2/4pt) Point Rolls Reversed: From inverted flight. 
Model rolls
   through 180 degrees, hesitating at each 90 degree point. Then rolls 
through
   180 degrees in the opposite direction hesitating at each 90 degree 
point. At
   each hesitation wings are parallel or vertical to the horizon. Center 
is
  middle of upright flight. Downgrades:
  1. One-quarter rolls more or less than
  90 degrees
  2. Model does not
  hesitate after each one-quarter roll
  3. Roll rate not constant
  4. Changes in altitude
  5. Changes in heading
  Two
   point (2/2pt) roll – slow roll reversed: Model performs a two point 
(2/2pt) roll, immediately
   performs a slow roll in the opposite direction. See descriptions 
of 
two point
   roll and slow roll for requirements and downgrades for all elements 
except
   centering. Roll rates need not be the same for the two point (2/2pt) 
and the
  slow roll. Downgrades:
  1. Centering. The center of the maneuver
   is determined as the middle of combined roll elements. Center is 
determined
   by the midpoint between the start of the two point (2/2pt) roll and 
finish of
  the slow roll.
  2. Roll reversal not immediate.
