Derry Turn

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.

Faults:

1. Entry not in parallel with the judges’ line.
2. The maneuver not centered in front of the judges.
3. The rolling maneuver in front of the judges not axial.
4. The roll in center not in the same direction as the entry to the maneuver.
5. The roll not carried out on a line directly away from the judges.
6. Any hesitation between the end of the first quarter turn, the roll and/or the start of the second turn.
7. Exit not parallel with entry.
8. Significant height difference during the maneuver.
9. The maneuver misshapen as seen as part of a figure eight.
10. The maneuver is executed too low or too high to be easily judged.
