Choosing among fpv frames & build kits starts with one practical question: do you need a bare platform for a custom build, or a package that includes the parts needed to get airborne? The ARS-5 V1.0 5 Inch 3D Printed FPV Drone Frame by Dave_C_FPV is clearly aimed at the first group. It provides the frame and its specified mounting layout, while the rest of the build remains your responsibility.
Quick verdict
At USD 12.00, the ARS-5 V1.0 is worth considering if you are assembling a 5-inch quad from separate components and want a frame with clearly stated fit points. The design is made for 5-inch propellers and includes a 19mm Micro Cam Mount, an SMA Antenna Mount, and mounting provisions for common flight-controller, 4-in-1 ESC, and motor formats. The important trade-off is equally clear: electronics, standoffs, and screws are not included.
ARS-5 V1.0 5 Inch 3D Printed FPV Drone Frame by Dave_C_FPV

The main reason to choose the ARS-5 V1.0 is its specific build layout. The description lists 20 x 20 and 30.5 x 30.5 flight-controller/4-in-1 ESC mounting patterns, a 16 x 16 motor mount, and space for 22xx and 23xx motors. That gives a builder concrete dimensions to match against the components already on hand. The 19mm Micro Cam Mount and SMA Antenna Mount also make the intended FPV equipment placement more apparent than a frame described only by propeller size.
Its other notable detail is the construction: the frame is described as 3D printed from PETG infused with carbon fiber material. That wording identifies the material makeup without promising a particular flight feel or impact performance. The frame also references 20mm alloy standoffs, but standoffs are not part of what comes with it.
Who it suits
This frame fits a hands-on builder who already understands the parts needed for a 5-inch FPV setup and wants to select those components separately. It is especially relevant when your camera is a 19mm Micro Cam and your build uses one of the listed controller/ESC mounting patterns. The USD 12.00 price also keeps the frame itself straightforward to assess before accounting for the rest of the hardware.
It is less suitable for someone seeking a bundled FPV drone build kit. Since the frame does not come with electronics, standoffs, or screws, you will need to assemble the remaining parts independently. That is not a flaw for a custom project, but it is a meaningful limitation for shoppers expecting a more complete package.
Meaningful trade-offs
The ARS-5 V1.0 offers useful specification detail for its format, but the listed dimensions should guide your component choices rather than imply that every part will fit. Check your intended controller, ESC, motor, camera, and antenna setup against the 20 x 20, 30.5 x 30.5, 16 x 16, 22xx, 23xx, and 19mm references before committing to the build. The frame's 3D-printed PETG-and-carbon-fiber construction is another clearly stated characteristic, not a substitute for evaluating your complete setup.
Bottom line
Choose the ARS-5 V1.0 when you want a USD 12.00 5-inch frame with defined mounting points and are comfortable sourcing hardware separately. Pass on it if your priority is included electronics or a ready-to-assemble bundle. For a component-by-component build, its clearest advantage is the amount of fit information attached to a frame-only purchase.
