Radio Control Scale Aerobatics
The objective of RC Scale Aerobatics is to demonstrate the precision and excitement of flying a Scale model replica in a manner that closely resembles the agility of the full-scale, world-class aerobatic champions of today. Following in the footsteps of the International Aerobatic Club, in which full-scale pilots fly a specific set of outlined maneuvers in front of a panel of judges, RC pilots perform a similar set of maneuver sequences designed to suit one of the three skill-level classes: Intermediate, Advanced, and Unlimited. The competition concludes with the Freestyle event, in which pilots fly an original aerobatics routine that lasts 4 minutes. The routines are typically choreographed to music and feature daring, low-level altitude stunts.
