From “Competitor’s Guide”:FLIGHT PATTERN/MANEUVER AREA:FLIGHT PATTERN/MANEUVER AREA:

All schedules to be executed in order given by the manual.

Uninterrupted flight for each round.

Infractions of any/all of following items cause downgrade(s):

Each maneuver must be clearly visible to judges.

Takeoff direction at the pilots discretion.

All maneuvers must be called so judges can hear (pilot or caller).

Each maneuver must have a “Start” and “Stop” call.

Maneuver performed each time model passes in front of judges.

Scheduled “Fly-by’s” are excluded from above rule.

All out-of-order maneuvers are Zeros, except landing.

Competitor’s Guide, cont.:GENERAL MANEUVER SPECIFICATIONS:GENERAL MANEUVER SPECIFICATIONS:

Maneuver Positioning:

Distance out to be no greater than 300 ft. (~100 meters) from pilot.

Exceptions: Procedure Turn, Flat Horizontal Eight & Traffic Pattern.

Maneuver tops no greater than 60 degrees up from judges’ viewpoint.

INDIVIDUAL MANEUVER SPECIFICS:

Each maneuver shall have a 50-ft. straight-and-level path preceding and following the first and last maneuver component.

Exceptions: Novice & Antique Sportsman Procedure Turn, following flat Figure Eight, and after completion of Traffic Pattern.

Landing to be announced as “Landing beginning at six feet.”

No bonus shall be given for exceptionally low maneuver placement.

Entry and exit altitudes should be consistent except for Immelman Turn, Three-turn Spin, and Traffic Pattern.

No bonus shall be given for excessively large maneuvers.

INDIVIDUAL MANEUVER SPECIFICS, continued:

Maneuver size should be proportional to the distance out it is flown.

Scores for each maneuver shall be based only on the skill with which it is presented and flown (not model appearance or performance, itself).

Presentation points:

MANEUVER DOWNGRADES, according to:

Type of defect.

Severity of defect.

Number of times a defect occurs.

Total number of defects.

Overall positioning of maneuver.

The Guide contains some examples of downgrades.

When a zero is given for a maneuver, judges must consult with each other about the justification for the zero.

MANDATORY ZEROS are to be given for:

Flying behind the specified flight line (zero line) during or between maneuvers.

Maneuver performed out of sequence.

Execution of an illegal (non-scheduled) pass in front of judges.

Competitor’s Guide, cont.:JUDGING SECTION:JUDGING SECTION:

MANDATORY ZEROS, continued:

Maneuver not completed.

Failure to take off.

Landing outside of runway or landing zone boundaries.

Touching of plane before completion of flight.

Stall Turns:

Flop: zero for single Stall Turn, five points for flopping one of two stalls (Double Stall Turn, Figure M).

MANDATORY ZEROS, continued:

MAJOR AND MINOR DEFECTS:

Downgrades for specific maneuvers:

Spins:

A snap roll entry.

Model not stalled on entry.

Less or more than exactly 3 spins

Over- or under-rotation on third spin, on point rolls, etc., should be downgraded proportionally to the magnitude of the error.

Major errors (lack of a straight line segment where one is required, stall turn radius exceeding 1 ½ wingspans, etc. should be downgraded 2 points.

Competitor’s Guide, cont.:JUDGING SECTION, continued:JUDGING SECTION, continued:

MAJOR AND MINOR DEFECTS, continued:

Point rolls must hesitate on the designated angle with equal time on each point.

One point is deducted for slight variations, while more severe mis- timing is further downgraded.

If one or more points are not visible, or there are more than the required number of points, the maneuver is severely downgraded (five or more points).

OFF-CENTER MANEUVERS:

Deduct two points for each ¼ of a maneuver that the maneuver deviates from exact center (assuming no permitted off centering from judges for sun).

For a loop whose edge just touches the center line, deduct four points; deduct 2 points for a ¼ of a loop offset.

USE THE OTHER ROLLING CRITERIA TO JUDGE THE THREE ROLLS. IF YOU WERE TO SEE THE BLACK AND WHITE ROLLS, THAT WOULD BE ABOUT A 45 DEGREE ANGLE. AT 1 POINT PER 15 DEGREES, THAT WOULD BE A DEDUCT OF ONLY 3 POINTS.

MOST WOULD GIVE THIS A DEDUCT OF SIX OR MORE WHICH IS NOT CORRECT. FOR EXAMPLE ANY TYPE ROLL GOING OUT LESS THAN 7.5 DEGREES SHOULD BE ½ POINT, NOT TWO OR THREE!

MANEUVER SCORE = 10

• FOUR POINT ROLL From a straight and level flight path, the model is rolled 90 degrees and holds this attitude, with the wings in a vertical position, long enough for it to be clearly defined. The model is then rolled another 90 degrees, in the same direction of rotation and holds the inverted attitude long enough for it to be clearly defined. This is followed by another 90 degree roll in the same direction, bringing the ship to another knife edge position. Following a similar pause in the roll, the ship finally rolls another 90 degrees to upright and level flight.

• Downgrades:1. Model not level at start of roll 2. The path traced by the model is not a straight line. (The plane

MANEUVER SCORE = 10READ THE MANEUVER DESCRIPTION CAREFULLY!

The following are a list of things you should take from this presentation if you don’t remember anything else. We strongly suggest you study the different maneuvers in this presentation. If you learn the reason for downgrades your flying will dramatically improve as will your ability to judge!. We could not show all the maneuvers and all the possible down grades. That said, we have a sufficient number so you should be able to judge any maneuver that is introduced, now flown, or introduced later.

1 Maneuver position with respect to the center line. The normal deduction would be two points for each ¼ of a maneuver that the maneuver deviates from exact center (assuming no permitted off centering from judges for sun). This is of course is based on the judges perspective. This will be discussed and demonstrated at the next in flight judging clinic.

•2 One point is to be deducted for each 15 degrees in the pitch roll and yaw. Likewise this will apply to the wing angle. You will notice and apply this rule where a turn is used to correct a maneuver by using the ailerons. You will see wings at an angle in entries, exits, loops and many other maneuvers. If the angle is between 15 and 7.5 degrees the discount is 1 point. If the angle is between 0 and 7.5 degrees the downgrade would be one-half point. Based on these numbers, let’s say a four point roll is perfect except it climbs 7.5 degrees, that would be a downgrade of .5 point. The same would hold true for a horizontal offset of 7.5 degrees. Many times if a judge sees a slight deviation on the horizontal line he will deduct up to two or three points. Remember the distance a four point or slow roll takes, it can go in or out at 7.6 deg. What would appear to be some distance. If it were 16 deg, it would only be 1 point. Also many times exits or entries to maneuvers may be at 15 deg. Remember the angles shown and this should •only be one point.

3 Geometry is a major consideration in judging a maneuver. For example, where a one-half or full roll is in a segment it normally should be centered in the vertical or horizontal line. You should be familiar with the maneuver to be judged. All maneuvers consist of straight lines, radius as in loops and portions of loops, rolls or spins.

4 The gracefulness of a maneuver is a consideration. Herky-jerky movements of any control surface is a downgrade. You will see this in horizontal rolls where the plane is popped with up elevator to get a more positive attitude to start the rolls. Based on the severity, this should be up to a one point deduction for each occurrence. You will see it in many maneuvers with incessant aileron and elevator bumping. If the wind causes a bump and it is immediately corrected, It should not be a down grade. The downgrade is a judgment call and will be discussed in detail at the in flight judging clinics.

• 5 Entries and exits. You should start with a good impression and exit with a good impression. Enter on a flat line with your wings level, exit the same way. Let us impress upon you, the first and last thing you do in a maneuver is probably one of the most important parts of the score you get.

• 6. If you are undecided about a score, the benefit always goes to the pilot. For example, if you are undecided if it’s a 9.5 or a 10, it should be a ten. Each judge should be capable of scoring a maneuver from ten to zero regardless if the previous maneuver was low or a zero. A novice pilot is able to do a ten as well as an expert pilot is capable of doing a zero.

• 7. If you are judging one of the lower classes, you should award the score earned. If a pilot does a four, don’t give them a six or seven to take it easy on him. You are doing him a disservice. The second judge may give him the appropriate score and needless to say he believes the higher one is correct.

• Common Sense…. When judging, do not carry on a conversation with anyone while the pilot is flying. If others are having a conversation to near to be a distraction, ask them nicely to be quiet. Most generally a finger over your mouth with a shush will suffice.

• If someone is in the area where the pilots may pick them up with their peripheral vision, have them move back.

• As a pilot if the next competitor is ready to fly, don’t carry on a conversation with the judges. As the next pilot you should have your engine ready to start when the landing is called complete . You won’t believe how much time this saves during a round of competition.
