WiFiLink2 OpenIPC 2 inch drone frame and "canopy"

When printed in PAHT-CF, it comes out stiff and sturdy. It is a light frame, around 15g. The VTX is mounted on the top plate. All screws used are m2 screws.

The top plate has 20x20 and 25.5x25.5 mounting holes for different VTX mounting options (O4 lite, HDZero, Walksnail Nano, etc). My build, and what it is designed for, uses RunCam WifiLink2 kit, where I only removed the fan and left the heatsink on. It is a 2s build, while the specification states 9-22V. However, as for now, it did not give me any problems. it works just fine on 2s (I assume that like the most of OpenIPC hardware, the components run on 5V internally). Nevertheless, do that on your own risk.

Camera mounting holes allow different sizes of the cameras. Smaller cameras (WifiLink2 includes quite large camera which needs to be mounted higher) can be mounted lower, which puts them closer to the front.

The model also contains a cage ("canopy") for mounting the AIO FC, VTX and the camera on a generic frame base cut from carbon fiber, which would allow for larger builds.

You can also print some of the included TPU mounts for the antennas, the GPS (HGLRC M100-5883) and a finder (IFlight YR50B_S). For my small build, I only used the antenna mount.

Parts in my build (if the included VTX to FC cable was shorter, no soldering would have been required):

• 4 Happymodel EX1103 KV11000 brushless motors for Mobula8/Bassline
• CrazyF405HD ELRS 1-2S AIO FC built-in UART ELRS receiver and 12A BLHELI_S ESC
• RunCam WiFiLink2 (Based on OpenIPC)
• A bunch of m2 screws
• Velcro strap for the battery

The total weight of my build is around 73g. Removing the heatsink or using a lighter VTX would further reduce the weight. The frame with the top plate uses only 15.31g of PAHT-CF filament.

Personally, I like the heavier version with the LiPo mounts at the bottom (better VTX cooling) and RHCP antennas (that match my Radxa GS), bringing total weight to 80g:

Edit: I have made the frame a little bit larger to make sure that the props cannot touch it, and I have added a 3 inch version:

Edit 2:

I made the 3 inch frame a little bit stronger at the motor mounts by increasing the thickness from 3 mm to 4 mm.

I have also added a 2 inch frame variant with 9 mm motor mounts for larger motors:
