The design and quality of this frame is the best in the industry, which is probably why it’s always sold out. I was fortunate enough to purchase two, and I’m grateful they re-opened sales to the U.S.

Built to Survive.
Tight gap. Full send. You're not thinking about your frame. You're thinking about the line. That's ERA.
This frame has been our bestseller for 1.5 years. The reason is simple: it survives. Crash into concrete, turtle out, keep flying. No walk of shame to retrieve your quad.
This is the O4 Pro Version. Same ERA. Same durability. Built specifically for the DJI O4 Pro camera with stock plastic housing. The larger O4 Pro camera required a redesigned cage and extended bottom plate front. Everything else stays the same.
Crash. Turtle. Fly. Team pilot @nils.vo on ERA.
The Cage: Why Injection-Molded Nylon?
The visual signature of the ERA is also its functional core. We don't use aluminum (too rigid) or 3D printing (too weak) for our camera protection. We invested in high-pressure injection molding because our testing proved it superior to every other method. 3D printing creates layers, microscopic weak points where cracks eventually start. Injection molding creates a solid, uniform polymer structure with equal strength in all directions.
Why nylon? It's the same polymer family used in downhill mountain bike pedals and high-end snowboard bindings. Parts that survive thousands of vibration cycles and high-velocity impacts without snapping. TPU is more elastic, carbon is stiffer and can chip on sharp impacts. Nylon sits in between: structural memory to take a hit and keep your camera exactly where you set it. It absorbs impact energy, flexes, and bounces back. It sacrifices itself so your electronics don't have to.
Beyond protection, this solid cage acts as a structural bridge. Combined with our split deck construction, the entire chassis becomes one unified, stiff block that withstands abuse.
The worst cage we've ever seen. One year of bashing by team pilot @scarce_fpv. Still functional.
Action Camera Mounting System
We fly 20°. That's why it's the stock angle. Five mounts available from 10° to 30° in 5° steps. One M3 screw out, swap the mount, done. The cage stays untouched.
Your FPV camera is separate and fully adjustable from 0° to roughly 40°.
Geometry & Handling
The ERA uses a Compressed-X layout to squeeze the frame footprint to the absolute minimum. This centralization of mass is what makes it feel snappy and locked-in.
Action cam sits close to the propline. This isn't aesthetic, it's weight distribution. The closer to center, the more responsive the quad.
One tradeoff: This geometry pushes props further out of your FPV feed compared to True-X, but they're not invisible. We prioritize balance and flight performance over a clean cinematic view. You will see prop edges in your camera.
Construction
Arms lock into the frame with a form fit. No slop, no play. The bottom plate is under tension from the center screw, adding stiffness without weight.
Need to access your stack? Leave the camera attached. Six screws out, top plate off, full access. Nothing to realign when you're done.
Every cage is checked by hand. Heat inserts installed with specialized equipment. No batch leaves without personal QA.
Material Standards
We build what we fly. That means no shortcuts on material grades. T700/T800 carbon mix with chamfered edges where it matters. 12.9 Grade YFS steel screws that don't strip. 7075 aluminum standoffs that don't bend.
What's Different on the O4 Version
- O4 Nylon Camera Cage: Redesigned for the larger DJI O4 Pro camera. Same injection molding process, same durability.
- Extended Bottom Plate Front O4: Longer carbon plate to match the O4 cage dimensions.
- Updated 3D Prints: O4 VTX Dual Antenna Holder, new TPU camera inserts.
What You're Getting
A frame that won't break in normal freestyle. Camera protection that actually protects. Hardware that won't strip, bend, or fail. A build experience that doesn't fight you. A quad that flies like it should.
Developed by pilots who crash, rebuild, and fly the next day. Every detail comes from real sessions, real crashes, real frustration with how things used to work.
