About 25 countries have teams that fly in international competition. International model rocket competition is organized under the auspices of the FAI (Federation Aeronautique Internationale), the international body for aerospace sport competition and records. Under their rules it is called "spacemodeling". An overview of international spacemodeling is provided on the FAI web site (https://www.fai.org/page/s-space-models). The latest (2023) edition of the FAI Sporting Code for Space Models is attached below.
International spacemodeling competition events are somewhat similar to NAR events (streamer duration, parachute duration, scale, and others). However, FAI events have model dimension requirements that lead to models and construction methods different from what is normally seen in NAR competition. The requirements are documented in the FAI Sporting Code for Space Models (the international equivalent of the NAR Model Rocket Sporting Code). The Space Models code is underneath the overall heading for aeromodeling on this page.
A World Spacemodeling Championships (WSMC) has been held by the FAI about every two years since 1972 (a separate class for Juniors began in 1994). Since 1992 these have all been held somewhere in Europe, usually Eastern Europe - but that changed in 2023, when the WSMC came back to the USA!
The eight events for a WSMC are defined in the FAI Sporting Code, are normally the same every time (with one important difference in 2023), and are the following:
- S1 - Altitude (S1A where the "A" refers to power class, 2.5 N-sec for Juniors; S1B, 5 N-sec for Seniors) (see S2/P below)
- S3 - Parachute Duration (S3A for Juniors and Seniors)
- S4 - Rocket Glider (free flight) (S4A for Juniors and Seniors)
- S5 - Scale Altitude (S5B for Juniors or 5 N-sec, S5C for Seniors, 10 N-sec)
- S6 - Streamer Duration (S6A for Juniors and Seniors)
- S7 - Scale
- S8 - Radio Controlled Rocket Glider (S8D for Juniors, S8E/P for Seniors - which will become S8D/P in 2025)
- S9 - Gyrocopter (Helicopter) Duration (S9A for Juniors and Seniors)
Also:
- S2/P - Precision Fragile Payload (similar to TARC) - which was also flown in 2023
The most recent WSMC, the 24th for Seniors and the 15th for Juniors, was held in Georgetown, Texas, USA, July 2-8, 2023. The next will be held back in Eastern Europe, in Zrenjanin, Serbia August 21-28, 2025.
