Pattern: mostly done by UGLY! planes, big smooth aerobatics, you have to get very anal about making your loops and stuff perfect, even flying in a straight line isn't easy possibly one of the most skillful disciplines

3D: the planes past the stall point, your flying on engine power alone, and it ain't flying the direction its meant to be. includes prophang, torque roll, all those weird spins that defy gravity. done by funflys and scalish Extra looking things, large surfaces and over powered engines required.

Aerobatic. a more realistic version of 3D, and less fussy than Pattern, using any plane doing things that real planes can do
