Flying Radio-Controlled (RC) model aircraft outdoors has a similar aspect to flying RC model aircraft indoors: aerobatic stunts can be done indoors as well! This site is to help provide some insight into indoor RC aerobatics.
Indoor aerobatics can be categorized into one of three categories: sport aerobatics, mild competitive aerobatics, and the F3P class for internationally competitive aerobatics. At least one of these categories would apply to any pilot desiring to fly some kind of RC aerobatics indoors.
The first category, sport aerobatics, consists of any indoor model capable of doing some form of aerobatics beyond level flight. Aerobatic maneuvers include rolls, loops, and stall turns. Many models could do stall turns. Depending on the type of indoor model, some can even manage a roll and loop. This is all sport flying: modelers having fun for the sake of having fun. Small common models of Night-Vapor, Sport Cub, Yak 54 and Extra 300’s are all examples of sport flying models that have some aerobatic capability.
The next category is beginner’s level competitive aerobatics. Models generally weight above 100 grams in this category and easily obtainable and also relatively in-expensive, meaning about the same relative cost as most other indoor RC models. These models can easily perform sport aerobatics and casual flying while also being competitive in the easier classes of precision aerobatics. Go to the menu link of Beginner’s Level within the Indoor Aerobatics menu to learn more about this category.
The last category is the most challenging for RC competitive aerobatics, consisting of the F3P Competition usually done at an international level. Models in this category typically weigh significantly less than 100 grams, in a fully ready-to-fly mode with batteries installed. Go to the menu link of F3P Competition menu item within the Indoor Aerobatics menu to learn more about this category.
