[NSRCA-discussion] Masters 2007 Figure "M" question

[White, Chris]

If someone has already clarified, I've missed it, but....

 

I thought it was to be assumed that "Flight Path" is ALWAYS the judging criteria (OK, except while the aircraft is auto-rotating in a spin....)....NOT model attitude.   (Gee, can you imagine how ugly the M would look in 20kt winds if NOT wind-corrected?)

I have a real problem with the rules for downgrades listed. It does not allow for wind correction.

 

"Model not vertical at start and finish of rolls and stall turns."

Should that not be "path not vertical" instead???

	http://nsrca.org/competition/judging/Patterns2007
	
	Figure M with 1/4 or 1/2 Rolls: Model pulls up into one-quarter (1/4) loop
	to a vertical track, hesitates then performs prescribed roll, hesitates then
	executes a stall turn through 180 degrees, hesitates, performs
	prescribed roll, hesitates then executes one-half (1/2) outside loop to
	vertical track, hesitates, performs prescribed roll, hesitates, executes a
	stall turn through 180 degrees, hesitates, performs prescribed roll,
	hesitates then recovers with another one-quarter (1/4) loop to level flight.
	Direction of rolls and stall turns are pilot's option. The length of the
	vertical segments is not a judging criteria. 
	
	Downgrades:
	1. Model not vertical at start and finish of rolls
	and stall turns.
	2. Stall turns not exactly 180 degrees.
	3. Model does not execute prescribed rolls.
	4. Rolls not centered in vertical lines.
	5. Bottom of outside half loop not at same altitude
	as entry and exit.

	Hi Jim,
	
	Unless the maneuver has changed from 15 years ago all the rolls have 
	to be in the same direction, resulting in one stall turn being 
	canopy-facing you and the other being belly-facing you (your choice 
	as to which comes first). It's a tough maneuver, especially when the 
	wind is blowing other than down the runway.
