"Tight Corner"

[Ken Culbertson]

The Judges Guide implies that a "Tight Radius" is from 4.9 feet) to 6.9 foot radius.  I am under the impression that most of us fly somewhere between 10 and 12' with a very few making it around 9.  This has my curiosity going again.  What is the radius of our top fliers and how did they stack up to the corners at Worlds.

Hit fleeze flame at say 2;26 ( triangle ) , print & get the measuring stick out .



An int , the lower leg SHOULD match the line length , & the hight too .
( If you stick a 50 gallon drum , and another the line length apart , on the circle outer .
* CORRECTION . oh dear . mithmotical ERROR , its 1/4 & 1/8th circumferance . *
Maybe shift em out a bit on the same sector line !  youll see 60 Deg / 1/6 th Circle
is a bit less than youd think , if you try'n stay insidem in squares and such . )

Dividing across by 13 if you assume 65 Ft. to center will get 5 foot devissions .
Just start throwing verticals at ends and horizontal lines at apex & base .

And AWAY you GO ! .

Triangles were too pretty to desecrate them.  I used the square loop.  His corners ranged from 1/4 to 1/3 of the maneuver width.  Assuming the standard 1/8 of a circle (51') and 65' lines that would be radius between 12' and 17'.

The entire rule book for the CLPA pattern only states one time the term "tight turn" used to define the corners of the square and triangular/hourglass figures should be "between 4.9 feet and 6.9 feet radius".  (Paragraph 14.7.1 in the Judges' Guide.)  I thought that any reference to a specific measure for the turn radius of these maneuvers (between 4.9 and 6.9 feet) had been purged from the entire rule book when the rule changes to do so were adopted.

(Thank you Ken for finding this for us.  This needs to be and will be addressed by the AMA Control Line Aerobatics Rules Committee in this two year rule change cycle which started in January, 2022.)

Basically, this reference to a specific turn radius in the Judges' Guide can be and is to be ignored.  The Judges' Guide, Paragraph 14.1.1 states that "The maneuver descriptions and maneuver diagrams of Paragraph 13 take precedence over any differences that might appear in this Judges' Guide."

OOPS .
No wonder its TIGHT .

The figures 1/8 th ' sector ' , 1/4 for squares .

Pacing , the lines are generally 17 to 22 .paces .
Its not hard to see 1/4 circle - 90 degrees . And half thats the 45 degree sector = 1/2 hight = tops of squares & rounds .

For visual markers to refine your shapes !  tho is the hourglass 1/6th or 1/4 circle on the base leg ( and top ) ?
