On day 3 of the Control Line Speed Nats, we flew Formula 40 Speed, 21 Profile Proto Speed, and Fox 35 Stunt Speed. There were a total of four flyers in 21 Proto, three entered Formula 40, and 11 flew Fox 35 Speed.

There are multiple Control Line (CL) events at the Nationals. They all share a bellcrank to control the elevator and fly in a circular pattern. But each CL event is very different in its purpose. The goal in a CL Scale event is to build a smaller version of a full-size aircraft in appearance and flight qualities.

On Monday, July 7th, there were three events being held: Old Time Stunt (OTS), Classic, and Nostalgia 30.

Simply put, Control Line (CL) Precision Aerobatics is an event where a builder of a model airplane is judged not only on how well they build their plane, but also how well they fly it in a prescribed flight pattern involving aerobatics.

Welcome to the 2025 National Aeromodeling Championships for 2025. My name is John Moll, I’m from The St. Louis, Missouri area and I’ll be filling everyone in on Control Line Speed events for the week.

The Navy Carrier event came about during the time that the US Navy sponsored the Nationals and they wanted an event with a Navy theme. These events consist of three separate sections, High Speed, Low-Speed, and Landing.
