Impossible? Not anymore.
A center joiner for the Cayley F5J*, made with WingBones Tendon technology. Continuous carbon fiber, embedded in a red polymer that bonds with the WingBones carbon fiber composite, laid along the path the flight loads take.
Key Features
- Holds its angle. The Cayley's joiner section is the smallest of any 4 m plane WingBones makes a joiner for. Tendon puts continuous carbon fiber where the load is, so the wing holds its angle under operating loads.
- Gives way when it should. Engineered to be the part that gives way in a very hard landing or a crash, close to the fuselage.
- Pilot-tested. Flown on a standard-layup Cayley, with clearly less flex in the air.
Two grades
- Light: for light, unballasted builds. Recommended all-up weight: F5J minimum to 1,350 g (47.6 oz). Coming soon.
- Standard: for standard and heavier layups. Recommended all-up weight: F5J minimum to 1,600 g (56.4 oz), ballast included. About 55 g.
WingBones Tendon™: continuous carbon fiber
Tendon joiners carry continuous carbon fiber, embedded in a red polymer that bonds with the WingBones carbon fiber composite, laid along the path the flight loads take.
Holds the line. Takes one for the wing. Under operating loads, the wing holds its angle. In a very hard landing or a crash, the joiner is the part that gives way, not the wing. Without that design intent a continuous-fiber joiner could be far too strong for a crash. No breakaway design is perfect, because no two crashes are the same, but the intent is built into every Tendon.
Bench-tested. Flight-tested. Every Tendon grade is flex and impact tested on WingBones test rigs, and each plane's Tendon design has been flown.
- Your angle. Choose a standard angle or a custom angle in 0.5° steps.
- Free shipping in the USA. Every Tendon joiner ships free within the USA.
