Default RE: Aresti question


ORIGINAL: gaRCfield

Well after reading the narrative side-by-side with the Arresti schedule, I am amazed at how foreign it looked before, and how simple it looks now! I do have a few questions though:

The schedule shows a start point (dot) and an end point (vertical line). Often they are at different "levels" or heights. Is this irrelevant, as the maneuver should really start and end at the same level (hammerhead, teardrop, sharks tooth, half reverse Cuban 8 all have what I'm referring to; obviously moves like split S start and end at two different altitudes).
This is mainly to be able to fit the sequence onto one sheet. If you look closely at the Aresti, you'll see a faint line connecting some of them together

What does the dotted red line mean? Just a reminder to evenly space the rolls, etc.?
Inverted or negative "G" flight

On some maneuvers, loops, 5/8 loops, etc. are shown rounded, while other pulls/pushes are angular. Can someone please clarify why that is? I thought all pushes, pulls, and loop sections should have equal radius.
Not all maneuvers have an equal radius. You can find out all of this in the judging guide. Let's take the sharks tooth as an example. When you pull the vertical line you want a nice crisp radius on the pull, not really hard but definitlive where on the 45 degree line the pull to level flight will not be any where near the same radius. Now the pull to the 45-degree line from the vertical line should be the same as the radius you used to pull to the vertical line so lets say it took you 3 seconds to pull to vertical, then the pull to the 45 should be three seconds, but then the pull to level does not have to be the same.

As far as part and full loops are concerned, the radius of the loop must be the same all the way through the loop or part loop.

Again, as I mentioned in the narrative, think symmetry. You do not want to have the judges asking themselves what did he just do, was that a part loop or did he actually pull 90 degrees so make your 90/45 pulls and pushes in such a way that there can be no doubt that is what you did

Here's the judging guide

Thanks guys! I'm psyched
There is a Judging school at Ray's Hobby shop soon that is being done by Tony Bonnano and Bill Lairsey. I would suggest you go to it if you can, you'll learn a ton, both are quite capable judges
