These models are replicas of full-scale aircraft.  They are judged for workmanship, accuracy of detail, and other factors.  They must fly and are scored on their ability to take off, land and perform other tasks.  Precision Scale aircraft are the most detailed models and must be accompanied with airplane documentation showing the model's fidelity to the full-scale aircraft.  Sport Scale requires less-precise detailing, and the aircraft are judged from a distance.  Profile Scale is similar to Sport Scale, with the added provision that the models have profile (slab) fuselages. In Sport and Profile Scale, flying increases in importance.

Welcome to the 2021 CL Scale Nats. I am excited that we can fly together once again. We will see what is new and what is the same. It seems like it has been a really long time since we have all flown together at the Nats because the 2020 CL Scale Nats was canceled due to COVID-19.

2020 Outdoor Nats to Proceed as Scheduled

After careful deliberation, the AMA Executive Council has agreed to not cancel the 2020 Outdoor Nats. This decision is aligned with state and federal guidelines for events concerning COVID-19.

The 2020 AMA Nats will take place to the extent that individual Nats organizers plan and conduct their respective events. Additional safety measures will be in place to protect our members, staff, and community. Nats participants and visitors to the International Aeromdeling Center will have limited access to AMA facilities and should anticipate a scaled-back Nats experience.

AMA is continuing to monitor the situation surrounding the COVID-19 pandemic and it’s impact on our upcoming events. Our final decision on moving forward with the Nats will take place June 10. AMA Special Interest Groups (SIGs) are also making decisions for their individual schedules, and some are choosing to make earlier cancellations for their events The following message is from Mike Barbee, president of the National Association of Scale Aeromodelers:
