The IMAC (International Miniature Aerobatic Club) Scale Aerobatics is a model aircraft competition series in which participants compete with models that faithfully replicate real airplanes. During the competitions, participants are required to perform various maneuvers and acrobatic moves with their aircraft, and the winner is determined based on scoring.
IMAC Scale Aerobatics offers a unique combination of precision and artistic expression for modelers. Competitors can participate in various categories depending on the type of aircraft they use, and they must complete predetermined flight routines. The evaluation focuses on the participants’ flying techniques, accuracy, and the precision of their maneuvers, and scores are awarded accordingly.
IMAC Scale Aerobatics not only provides entertainment and challenges for the competitors but also offers an exciting spectacle for the audience as they watch the models perform various acrobatic maneuvers in the air. This sport combines a passion for aviation with the art of modeling and allows modelers to showcase their skill and creativity in the field of aviation.

The IMAC – International Miniature Aerobatic Club
Originally started as a special interest group within the American AMA modeling organization, IMAC has grown to become a global representation of precision aerobatics competition. IMAC is a nonprofit organization that focuses on educating pilots and maintaining the rules of the sport.
At the competitions, groups of pilots meet and compete following specific rules. Pilots perform predetermined maneuvers in front of judges. The initial score for maneuvers is 10, which can be deducted for errors or deviations. The routines typically consist of 8-10 maneuvers.
Just like in full-scale competitions, pilots are divided into classes, which become progressively more challenging. Each class has a “known” routine published each year, and it’s flown at all events in that year. In higher classes, pilots also have to present an “unknown” routine, which they see for the first time at the event.
Scoring is based on a “round-robin” system, where all pilots in the same class fly the routine in front of the same set of judges in one round. Pilots are ranked within this round. Judges are rotated, and pilots re-fly their routines. According to the rules, the pilot’s lowest round score (or rounds) can be dropped. Ultimately, the pilot with the highest score wins the event.
There are five main classes:
- Basic – Introductory level with basic aerobatic maneuvers. In this class, pilots can fly ANY size aircraft, and it doesn’t have to be a competition model. This class only flies a “known” routine.
- Sportsman – Maneuvers are slightly more challenging, and pilots are now required to use competition model aircraft. “Unknown” routines are introduced in this class.
- Intermediate – Maneuvers become more challenging, with somewhat more complex figures introduced. “Unknowns” are also more difficult.
- Advanced – In this class, pilots must be able to fly almost any figure. The challenge here is that the routines are more complex, including more intricate figures.
- Unlimited – It means exactly what it says: no limits! In this class, pilots face the most challenging routines and the most complex “unknowns.” It’s a real test of both the pilot and the aircraft, requiring developed experience and skills over time.
In addition to the basic competition classes, some events may have two additional classes:
- Free Style – Impressive performances in front of the audience! Aerobatic flying to music! There are no predetermined figures in this class; anything goes! Pilots are judged based on creativity, musicality, and overall piloting skills. The free style competition is not available at every event, but it’s the most popular part for the non-flying audience. The free style competition is open to pilots of any class, but the pilot must also participate in a main class competition.
- Seniors – The best pilot in the 55 and over age group, judged across all classes (except basic).
In 2023, the IMAC EUROPEANS competition was held in the city of Leszno, Poland. You can find great and spectacular videos of this competition and its days, showcasing incredibly beautiful aircraft as well.
