Pilot Qualifications

Pilots must show proof of being current members of the AMA. Unsportsmanlike conduct by a pilot, caller, or crewmember is grounds for the pilot’s disqualification from the event.

Scale Requirements

The only models qualified to be entered in a RCPRO Warbird 80 event must be scale models replicating heavier than air, fixed wing, propeller driven, man carrying, military aircraft that were in production after January 1, 1937, or scale models of non-military aircraft that have raced in the unlimited category of the Reno or Mojave Air Races or in an unlimited air race affiliated with the Unlimited Air Racing Association. To "have raced" means that the aircraft must have crossed the starting line while participating in an official heat. Civilian markings, paint schemes, & modifications to military aircraft are allowed. Civilian aircraft that were not designed for, but can be documented and were used by the military, will be allowed. All models must have a full fuselage, no profiles allowed. If you have any question as to whether your particular airframe will qualify for warbird racing, please contact the Contest Director prior to bringing it to the event.
