Roll

From straight and level flight, the model aircraft rolls at a constant rate through one complete rotation and resumes straight and level flight on the same track. Low powered aircraft would be expected to execute a shallow dive at full throttle before the maneuver. Competitors should nominate any special type of roll that will be performed, e.g. Slow, Barrel, Snap.
