Joy is a brand new 2.5-meter F5J glider released at the end of 2021 by the High-Quality team.
Thanks to its wingspan it combines a performance that can be compared to the 4m ships but at the same time plays a part as an entry-level F5J competition model.
Our tests found that Joy can perform on a similar level to the bigger wingspan models in the hands of a skilled pilot. And since the Joy is smaller in size it can be assembled at only 650g AUW in the light layup.
The core of this design is a combination of the low-drag fuselage, AG-series airfoil wing, quality materials, and the experience of the team behind it.
You can choose to purchase the Joy as a kit and build it on your own or choose a Receiver-Ready option instead.
For your convenience, here is a Joy F5J Build Guide
Pro Tip: secure your fuselage hatches with a tape holder to keep them in place under load in flight.

Joy F5J Glider Features:
Joy features everything you need for the afternoon thermal soaring as well as any F5J competition:
– Lightweight airframe including an XPS-foam core wing. Can build as light as 615g.
– Low-drag fuselage with two gear access hatches – a traditional in front and an extra one under the wing.
– Single-piece fuselage that is both light and strong and will fit up to 28mm diameter motor in front.
– High aspect ratio polyhedral wing that has great performance in weak thermals and at high speeds while returning from the downwind.
– Ballast enclaves in both wings allow adding weight to your glider when needed. The wing breaks downs into 2 halves and holds in place with sticky tape.
– Pull-cable & torsion spring installation for tail controls for less weight on the tail.
– Fully removable tails. The model breaks down to a 1.30m long box for transportation or storage.
Joy is available in Regular or Light carbon layups, and also in Fiberglass. The fuselage and tails are always carbon-skinned for saving weight and adding stiffness.
The glider kit includes an accessory pack that contains control horns, servo frames, pull cables, cable crimps, bolts, torsions, CNC machined firewall, pushrods, and wing harness pigtails. The other part of the harness comes pre-installed in the wing, so you just plug in your servos after installation and cover them with provided CF patches.
