Classes are important for the following reasons:
- They level the playing field so one pilot doesn’t have an advantage over another by using more powerful equipment. This allows the pilot’s skill to win the race, not their equipment.
- Aircraft builds can be planned with confidence that they will be accepted into competition.
- To ensure radio equipment is compatible with fellow pilot’s equipment as to not cause interference.
Props must be fully surrounded by covers or ducts.
