I wanted to know list of international aeromodelling competition happening this year and later next year.
Too many to list.
Depends on:
1. Type of aircraft you are interested in
2. Countries you are interested in
3. Participant or onlooker
Here’s an example

Best of luck with whatever you’re looking for.
