Even though the loop is lower k I would not forget it I would burn plenty of gas on it! The loop is a building block. The Cuban 8, and reverse Cuban 8 has a 5/8 loop. the humpty has a 1/2 loop. and the figure 9 has 3/4 loop. olmost every maneuver has 1/4 loop entry and exit. Master the loop(and rudder correction, and you are well on the wat to being proficient in all the rest of the maneuvers.
