ParkZone Vapor - EFlightWiki: "The Vapor is primarily designed for slow indoor flight, and is an excellent performer in this regard. It is capable of high-alpha flight at very low speeds and can turn rapidly, enabling flight in confined spaces. The flying weight of 15g makes the Vapor highly responsive to throttle and control inputs, and the low mass prevents damage in most crashes. The low weight also makes the Vapor sensitive to wind, including currents from air conditioning. Outdoor flight is possible only in dead-calm conditions."
