Franken,
You are not ready for the loony bin. You are right on the money. Loop, roll, straight flight, and spin (or autorotation) are the basic forms of flight that all other aerobatic manuevers are formed from. Some people include take-off and landing, but these are not basic forms of aerobatic flight, they are basic manuevers.

Example: A Cuban 8 is two 5/8th loops with 2 stright lines and two half rolls.

Example: An avalanche is a loop with an autorotation on the top (a snap is an autorotation just like a spin but nastier).

Regards,
Mark
