Can my club make rules that are different to those of the MAAA?

All MAAA clubs are totally autonomous bodies and they can make whatever rules they like as long as they comply with the law of the land, which includes CASR Part 101 A, B, C and G, and also comply with the MAAA Manual of Procedures. However they can decide to have additional rules that go beyond those requirements. As an example there are clubs that specify electric model aircraft only because that is the only way that they can obtain a flying field.
