What is F5J?
F5J, is an unofficial designation for electric sailplane contests. The planes use electric motors to power the gliders to an altitude where, after shutting off the motor, they begin thermalling.
Rules vary, but contests usually limit the motor run time. Then the pilot tries to keep the plane in the air for the target time, typically 10 or 15 minutes. There are often landing points for landing near a predefined spot.
For complete details on the rules we use in the ASA please see:
We have only just started using this latest version of the rules. You can check out a contest report on how this worked out at:
