[NSRCA-discussion] Emailing: Omega

I like the geometry. Rather than the 1 ½ snap from knife edge, how about a
reverse knife edge across the top. That gets George’s use of opposite rudder
into play.

George,

Do you really think that a knife edge loop is an advanced maneuver?  I like
the geometry of this maneuver and your thoughts about proposing something
different.  However the 1 1/2 snap on a looping knife edge really does put
it into an FAI category.  

Keep in mind this maneuver may not be that difficult on a sim but factor in
real life conditions and any kind of wind condition and this maneuver could
be all over the place considering knife edge and the 1 1/2 snap.

Obviously, the entry and exit radii require the same radial arc and should
be no more complex to judge than the four 

corners of a square loop.

Eliminating the snap and a half at the top as suggested by Ramsey would
relegate it to the status of an Advanced 

maneuver. The difficulty of the KE loop is 90% in the bottom half, which is
completely missing

here and the snap is included to increase the difficulty factor by requiring
the change to opposite rudder.

No, that works for me as a flier, but a specific radius may be difficult to
judge consistently. 

I've felt for a long time that that the maneuvers in our sequences utilize
three different radiuses full height and half and full height loops and
small radiuses used in facetted loops such as triangle, hex, octagon and
square. 

I would not have a problem pulling a small radius sufficiently before center
to intersect with a centered full size loop, the bottom of which if
projected round would be at entrance or base line altitude, but again it may
be hard to judge.

My feeling here is that,..........if we now have maneuvers that make
allowance for different roll rates, maybe we should 

consider making an allowance for a maneuver with different, but specified
radii. Especially if it offers up some thing new

and a break with the status quo.

It's probably too much to ask.......................

George if it is to be flown with equal radiuses it looks considerably
different than the attached drawing. An equal R drawing is attached here.

In any case it would be interesting to fly.

I've been thinking about this maneuver for quite a long time and thought I'd
pass it along for consideration by the Sequence Proposal guys.

It's meant to be a Masters level maneuver and while it contains no
integrated rolling elements it has some challenging elements. It's a center

maneuver like an M and requires a deft hand to present with symmetry and
grace while still being a "safe type" execution maneuver, in that it's a

looping maneuver performed AWAY from ground level from an upright position
with an upright exit, so the pucker factor is minimized.

It's called an Omega, which should be easily understood by it's apparent
shape. Here's how it goes.  See what you think :

We're approaching center flying from left to right. At a point before
center, a distance equal to 1/4 the radius of the loop, the model pulls
through

a radius of 135 degrees to a 45 degree up line and immediately pushes into
the arc of an outside loop which is flown to the nine O'Clock position

where the model performs a 1/4 roll to knife edge and continues the radius
of the loop to the 12 O'Clock position where the model performs a One

and one-half snap and continuing the loop radius to the 3 O'Clock position
where the model once again performs a 1/4 roll and immediately pushes

to complete the remaining looping segment and completing the maneuver by
pulling through a 135 degree radius to exit in upright level flight.

There's nothing really hard here guys, but the maneuver does demand
respectable concentration. Think of it as a strangely entered loop with a
knife-

edge loop across the top 180 degrees with a snap and a half avalanche at the
top. Roll and snap direction are pilot's option.

Don't be too quick to discount it. I've only done it on the Sim, but if I
can do it, it should be cake for the Masters guys.
