1. Core Advantages - Three Ways the Bent Tube Takes a Landing
A pre-formed bend flexes and returns. A straight rigid tube transfers the landing shock straight into the frame. A bent carbon strut flexes, absorbs the energy, and springs back - that's why curved landing gear survives the rough field.
No holes drilled in the loaded leg. Every hole in a loaded tube is a stress concentration where the crack starts on a hard landing. We fit ends with clamps, not bolts through the wall.
Wall thickness tunes the spring rate. Thin walls = light and lively; thick walls = firm for heavy payloads. We match the wall to your all-up weight so the gear works, not just survives.

2. Parameter Table (Typical Values, by Load Class)
| Load class | OD | Wall | Bend note |
|---|---|---|---|
| Light (≤5 kg) | 16 – 20 mm | 1.0 – 1.5 mm | U-bend, light flex |
| Medium (5 – 15 kg) | 20 – 25 mm | 1.5 – 2.0 mm | Tuned flex |
| Heavy lift (15 kg+) | 25 – 30 mm | 2.0 – 3.0 mm | Firm, payload-rated |
| Build parameter | Typical value |
|---|---|
| Material | Prepreg carbon, autoclave-cured |
| Layup | Fiber orientation tuned for flex |
| Ends | Clamp-mounted, no through-holes |
| Cross-section | Round or square |
| Length | Cut to your design |
| MOQ | Sample order accepted |
Typical industry values; bend profile and wall locked from your airframe and approved sample.
3. Customization - Bend to Your Frame
Send your landing gear drawing - bend angle, leg height, spacing.
End fittings - clamp blocks, foot mounts, or bonded sockets per your frame.
Color / finish - glossy, matte, colored gel on request.
Sample first - land it, check the flex, then produce.
4. Company Advantages - Bent-Tube Manufacturing, Export Ready
We bend, not just cut. Bent landing gear needs tooling and cure know-how - we hold that in-house, not outsourced.
Consistent bends. Same tooling and cure cycle after sample approval; reorders match.
Batch traceability. Material lot and layup documented.
Flexible shipping. Express for samples, sea freight for bulk.
5. FAQ
Q: Will the bent tube spring back after a hard landing? Designed to flex and return within its working range; extreme overload can permanently bend it - match the wall to your landing loads.
Q: Clamp or bolt at the ends? Clamp. Through-holes in the loaded wall invite cracks; clamp blocks spread the load.
Q: What OD and wall for a heavy-lift frame? Typically 25–30 mm OD, 2–3 mm wall. Tell us your all-up weight.
Q: Can you match our existing landing gear bend? Send the tube or drawing; we match the profile.
