The glider has an extreme flying envelope being able to handle a low-level lift as well as strong winds.
For better convenience, the ballast tubes are located in the wings and allow for a fast weight change during the pause between the competition rounds.
The wingspan is only 2.5-meters which allows pilots to hunt for the low-level thermals, just like with the 4-meter ships.
You can purchase this model as a kit and build it on your own or choose a Receiver Ready option and let our professional team build it to your preference – with servos and powertrain.
If you prefer to build it on your own, please, refer to the images below.

Joy F5J Setup Tips
For FrSky or OpenTX / EdgeTX users, we reccomend SoarOTX F5J template for radio setup.
It is free and extremely easy to use.
Additionally, it provides a flight scoring system which will come in handy during trainings or simple time keeping.
Since the wing has a composite construction, check the video below for identifying a “flat” position of the control surfaces relaative to the wing body.
