Masters 2005 questions

[Eric Henderson]

The Figure-9 as, an end box maneuver, allows the pilot to make the vertical line suit the needs of the next maneuver. As Matt says the half roll is centered in the vertical down-line. [The vertical line begins when the three-quarter loop ends and the quarter loop begins] The roll can be  "right at, above or below where the three-quarter loop starts". Said another way, the horizontal entry point to the three-quarter loop is not related to any components, such as a half roll, on the down line.

The snap at the bottom of the loop is an upright positive snap so it cause the attitude of the nose to pitch up but due to gravity the track stays pretty much on course. You will find that you snap just before the bottom of the loop and add power as you come out of the snap.

Sure its a challenge but you are called a Masters pilot, because you meet and master the challenge.

Regards,

Eric.

  Ed, the radii in any maneuver including the end-stage Fig 9, shall be the same. Since the Fig 9 is an end-stage maneuver, it's a height adjusting maneuver. The roll should be performed on the center of the vertical line, meaning right at, above or below where the 3/4 loop started, depending on the size of both the loop and the vertical.

  Any snap should show a "break". Since the snap is an inside snap in the Rev Ava, showing a very quick break shouldn't be a problem, if you use sticks for the snap. Also, you might want to hold elevator a bit longer than in last years's snaps, so that the nose will finish high. In essence, you are burrying the snap on purpose. This is easier to do right than some of the other stuff we've done.

    Hey everyone.  Have a couple "picky" questions on the figure 9 and avalanche.

    1)  On the figure 9, is it an "altitude adjusting" manuver?  By this I mean does the 1/2 roll have to be centered on the horizontal line the manuver started on?  Another way of looking at it is does the size of the 3/4 loop dictate where the 1/2 roll should be or does the length of the vertical line from the end of the 3/4 loop to the start of the 1/4 loop pullout dictate the centering of the 1/2 roll?

    A person start at a medium height, then do a huge 3/4 loop, not leaving enough room to center the 1/2 roll on the horizontal line with equal before and after lengths, so do the roll early(above the horizontal starting point) but keep the roll centered in the downline.

    2)  Does the radius of the 3/4 loop have to be the same radius as the 1/4 loop pullout?

    3)  On the reverse avalanche.  If we are to maintain the radius of the loop, how do we keep a slight downward radius when having to pitch up for a positive snap, then 1/2 way through the snap begin a very slight upward radius while finishing the snap.  Just food for thought.  I think the bigger the manuever the better to hide this little radii problem.  Any other thoughts.

    Thanks in advance.
