The annual Joe Nall Fly-In hosts its fair share of unique aircraft, and RCScaleAirplanes captured two of the best in flight in this video. Ali Machinchy’s F-104 1/4-scale Starfighter is 16 feet long and powered by a B300F turbine engine. The Airworld model was built by Trond Hammerstad in Norway and sports paint and markings from Ralle at Tailormade and a pilot figure from Tailored Pilots in the UK, so it’s truly international endeavor. The 1/4.2-scale Supermarine Spitfire Mk IX model was built by U.S. modeler Simon Bartlett and is piloted here by Austrian Thomas Gass. It’s a CARF kit and is powered by a three-cylinder, four-stroke 150cc KOLM engine that looks terrific un-cowled.
