itsFPV ERA 5-Inch O4 Frame Kit

Description

Built to Survive

Tight gap. Full send. You’re focused on the line, not your frame. That’s what ERA is all about.

This frame has been itsFPV’s bestseller, and for good reason: it lasts. You can crash into concrete, turtle it out, and keep flying—there’s no walk of shame to retrieve your quad.

Introducing 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 an extended front bottom plate. Everything else stays the same.

NOTE:

• Frame kit only: Electronics, ELRS antenna holder, and action cam mounts are not included.
• O4 Pro with stock plastic housing only. This frame is designed exclusively for the DJI O4 Pro camera with its original plastic housing.

Crash. Turtle. Fly. Team pilot /xe3N3bcmvJFwB7fSemqLuC017mk83MSZPgnFJ202dYwV4?autoplay=muted&loop=true&muted=true”>

The worst cage we’ve ever seen. One year of bashing by team pilot /DJxFQlroE001201UhGtvZx9UycDaJa777O3e4CNdAVlFU?autoplay=muted&loop=true&muted=true”>

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.
