The purpose of flying the Lazy 8 is to get you into flying inverted. The next thing after being able to fly inverted for a few laps is to do outside loops, as that is the next maneuver in the pattern and that is done by starting from inverted level flight. After you get used to that, doing outside loops from upright will require some extra altitude and knowing that you and your model WILL clear the ground with about 4 to 6 feet to spare. By the time you get this far, your brain should be getting used to the idea of doing that successfully. The only time you really need to do it in competition is if flying Old Tyme Stunt and you desire to enter the loop from upright. It can be entered from inverted also. Getting used to doing outside loops give you some confidence in starting the outside square. They both require that initial "down" input to get started that you have to gain the intestinal fortitude to do repeatedly and confidently. Once you are at that point, then you work on doing it correctly as per the rule book with all four sides straight. Most every on tends to do the outside square with a sort of roundish front side, but repeated practice and trimming out of the airplane and fine tuning power plant gets you there. If you can do a respectable reverse wing over, you will get used to the outside square eventually.
