[NSRCA-discussion] Proposed Masters Sequence for 2009/2010

Thu Jul 26 17:32:13 AKDT 2007

Jim,

I think the more you review and evaluate maneuver difficulty and the
assigned KFactor, the more you will find discrepancies.  And then..when you
start looking at the relative difficulty of a series of maneuvers, it
becomes very apparent two series of maneuvers with equal KFactors are
anything but equal when it comes to actually flying them (especially in
different wind conditions).  While KFactor can (and is) an indicator of
difficulty, the bottom line for turnaround sequences is that total KFactor
and individual maneuver KFactor can be quite misleading.

Regards,

Dave Lockhart

I heard there was a change proposal for masters in the works. After trying
to fly the current Masters sequence I was having second thoughts about
moving up anytime soon. The current masters is a big jump up from advanced
and is probably more appropriate to a 150-degree box (2 point slow roll
reversed).

Masters, being the top AMA class should maybe have more than one K-5
maneuver. I actually like the figure M with 3/4 rolls. It is not
particularly difficult to fly but very challenging to fly well and easy to
judge. The square horizontal eight takes a lot of flight time and is
difficult to maintain judging references.

I printed the proposed sequence and will try it, hopefully this week.

Thanks

Jim Hiller

Over the past couple of months we (the NSRCA board) have received a number
of comments about the Masters sequence that was selected in 2005.  We heard
that the sequence had too many snaps, turnaround maneuvers did not allow
positioning of the plane (in or out) after the 5th maneuver, and that the
difficulty level from Advanced to Masters was further increased.  There was
also an error in the schedule in that one would come out of the Double
Immelman (#10) inverted and head into the Humpty Bump (pull-push-pull) and
head into the ground based on the description.  The Masters schedule was
published in the July 2005 issue of the K-Factor (Option A on page 25) - in
order to correct the error, maneuver #9 was modifed to a 1/2 Square Loop
with 1/2 Roll Down instead of the 1/2 Square Loop with 2/2 Pt Roll Down.

The board felt that the original Masters sequence committee should revisit
the schedule to look it over and perhaps make modifications.  The original
committee was Troy Newman (chair), Ed Alt, Dave Lockhart, Joe Lachoswki,
Arch Stafford and Bob Pastorello.  Bob dropped out since he no longer flies
pattern.  Troy and the team started working on it but Troy couldn't devote
100% of his time to it due to the Nats approaching and his commitment to
trying to make the US team.  Dave, Ed, Joe and Arch worked the sequence but
decided that it would take too much modification to correct.  Instead they
came up with a revised schedule that the board felt was a worthy
replacement.  The board would like to submit this schedule to the Contest
Board to be considered as a replacement for the original schedule.

What do we need from everyone?  We'd like to get your opinion on the
sequence that was selected in 2005 and the new schedule that was created by
the sequence committee to address the issues that were raised by a number of
pilots.

Here is the sequence that was selected:

3       Top-Hat with 1/4 Rolls, Exit INV        2      
4       Cuban 8 with Full Rolls, Exit INV       4
