The Competition Regulations: General Information all categories, page 10 Section 8. Proxy Flying: A proxy flier may be designated by the builder only in those cases where the CD is convinced of the physical inability of the builder to fly the model himself. The proxy flier must be of the same age classification as the builder or, if younger, must have the Event Director's approval after he has assured himself that the younger pilot is capable of flying the aircraft. Inexperience or absence shall not be considered physical inability within the meaning of this ruling. It shall be required, in cases where physical inability is not readily apparent, that the builder produces written evidence to this effect from a competent authority. Proxy flying is specifically prohibited in the following events: Outdoor Hand-Launched Glider, Indoor Hand-Launched Glider, Control Line Combat, Control Line Navy Carrier, Control LIne Aerobatics, and all Radio Control events.
