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.

Day four of the AMA RC Scale Aerobatics (International Miniature Aerobatic Club [IMAC]) Nats greeted us with cooler temperatures in the mid-50s and steady wind gusts of 5-10 mph. The weather held steady, allowing for a full day of flying, and tomorrow's forecast looks promising as well.

We waited too long for the ceiling to clear…
Day two of the AMA RC Scale Aerobatics (International Miniature Aerobatic Club [IMAC]) Nats started with a low ceiling, delaying our flights until 1:30 p.m. While waiting for the skies to clear, pilots swapped stories and jokes, including a baffling tale about getting a negative score on a maneuver—say what?!
