F5J Information Rules and Resources

An introduction to F5J electric thermal glider rules - the new international rules that take the emphasis off a fast climb and expensive models.

F5J is a fast growing class of electric powered gliders that fly for 10 minutes in a 10-minute window after climbing for up to 30 seconds under power and starting from as low a height as possible. A link to the rules is at the end of this page.


Here you can also get an article about how the rules work, and how to fly the event.

 Many AEFA events and our Postal Competition now include F5J, to foster the Aussie experience with the event.  All this is designed to promote the rules and develop expertise and an understanding of the event.

So, if you have an electric glider with a moderate climb, that thermals well, and you can land it at your feet, give F5J a go!  These flyers did.
