COBRA ROLL  From upright straight and level flight, the plane pulls up into a 45 degree climb, performs on complete roll at a moderate rate, continues the 45 degree climb for a moment, goes over the top in what amounts to one-fourth of an outside loop and heads down at a 45 degree angle.  Another complete roll, equal in length and time to the first, is performed, and finally, the plane pulls out at the same altitude and heading as the beginning.    3

Downgrades:

1. Entry is not straight and level

2. Climb is not 45 degree angle to ground     

3. Roll path traced out by model is not a  straight line (I.e. plane barrel rolls or suffers change in heading) continuing in 45 degree climb

4. No momentary straight flight between first roll and 1/4  outside loop or between 1/4 outside loop and second roll

5. Flight path coming down is not at 45 degree angle to ground

6. Second roll is not at same rate as first 

7. Roll path of second roll is not as described for first roll

8. Pull out to level flight is not at same altitude and heading as entry
