Cobra Roll

Cobra Roll

Sport, Cobra Roll

Cobra Roll (aerobatic only) - The model starts in straight and level flight, pulls up into a 45 degree climb and executes a half roll to inverted. It then completes a 1/4 inside loop into a 45- degree dive, executes a half roll to normal attitude, and recovers to level flight at the same altitude and heading as the start. The highest point of the 1/4 inside loop should be on the judges' centreline. 

Errors:
x Manoeuvre not performed in a vertical plane that is parallel with the judges line
x Quarter loop is not centred on judges position
x 45° climb and descent paths not achieved
x Half rolls not centred in climb and descent part of figure
x Model does not exit manoeuvre at same height as entry
x Inappropriate use of throttle
x Manoeuvre too far away, too close, too high or too low
