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
