The model approaches at a high speed in straight and level flight on a line parallel with the judge’s line. The model aircraft then makes a steep (in excess of 60° bank) one quarter circle turn in a direction away from the judges, without loosing height. When centered in front of the judges the model aircraft makes a half roll in the same rolling direction as the entry, again directly followed by a steep one quarter circle turn in the opposite direction, and then flies off straight and level on a line parallel with that of the entry to the maneuver. The maneuver should be smooth and continuous.
- Entry not in parallel with the judges’ line.
- The maneuver not centered in front of the judges.
- The rolling maneuver in front of the judges not axial.
- The roll in center not in the same direction as the entry to the maneuver.
- The roll not carried out on a line directly away from the judges.
- Any hesitation between the end of the first quarter turn, the roll and/or the start of the second turn.
- Exit not parallel with entry.
- Significant height difference during the maneuver.
- The maneuver misshapen as seen as part of a figure eight.
- The maneuver is executed too low or too high to be easily judged.
