[NSRCA-discussion] Judging question for the experts

[Bob Kane]

One of my observations from watching the top competitors is their ability to "hit" a line after radius.  I'm not sure how to describe it, but you know when the radius ends and the line starts.

As long as
thin is an open discussion, where do we draw the line between easing into and
out of a radius? While appearing very smooth, may in fact be a variation from
constant radius. Slow flight also tends to mask the start and stop of radiuses,
which need to be at least noticeable to define geometry.

 Don,

This question of course relates to the Annex 5B –F3 R/C Aerobatic
Power Model Aircraft Manoeuvre Execution Guide, Section 5B.9...
5B.9 SMOOTHNESS AND GRACEFULNESS OF THE MANOEUVRE 
"Concerns the
harmonic appearance of an entire manoeuvre. Ie maintaining a constant flight
speed throughout the various manoeuvre components, like in climbing and
descending sections contributes significantly to smoothness and gracefulness.
Radii performed very tight or very loose, though being of equal size within one
manoeuvre may be subject for downgrading Smoothness and Gracefulness."
If the radii are very
abrupt the maneuver would not be "smooth and graceful."
 Similarly, if the radii are very loose the maneuver elements would likely
not be well defined (not graceful?).  I think "very" is the key
word - beyond expectation, not normally seen, etc.  Extending that
thought, I think this would be a uncommon downgrade.
Stating the obvious
here...there are no technical criteria for what constitutes "very tight or
very loose" radii.  The criteria are subjective.
Regards,
Andre Bouchard

A question on radius
judging.  Tight radius (or loose radius) manevuer segments are subject to
downgrade in FAI.  What constitutes a tight radius?  Physically tight
(in feet, for example), or tight (fast speed through the radius giving the
impression that the plane is pulling excessive g's, however that is
interpreted).   A slow flying radius could be extremely tight, for
example the last radius at the bottom of the triangle loop (135
degree pull) or figure Z.
Best regards,
Don
