I was fairly impressed with the quality of the GEP130X, so I decided to try out their flagship 5" frame, the GEP-TX. It's fairly well thought out and includes a few bonus components like the WS2812B LED panel and a battery plate with foam feet.

It doesn't say it in the product name, but this FC is an Omnibus F3 clone. I also have a genuine Omnibus and they both perform identically. I flashed Betaflight 3.1 and updated the ESCs to run dshot and everything seems to work as expected.

Challenges

There were a couple challenges, so I'd like to point them out and offer my solutions.

Fitting the FPV camera is a challenge. You'll need to screw one side panel to the camera before fitting it into the top plate. Once you've got it in place then slide the other side through the top plate before screwing it onto the camera. Once that's complete you can add the standoffs and HD camera mount. Depending on the size of your RX you may have trouble finding an appropriate place to mount it. Since I'm using a Spektrum diversity satellite it was small enough to ramp down the front of the FC below the FPV camera. I've got it antenna side down so I can run the antennas behind the front arms. They'll be far better protected here rather than on top.

Considerations

In the future I won't be using separate ESCs. Compared to a 4-in-1 build this was far more time consuming. I think we've reached a point where a 4-in-1 likely won't fail due to electronic failure. ESCs are far more prone to environmental damage being exposed on the arms. If you do choose to use separate ESCs you'll want to replace the kit PDB. It's very poor quality. Ideally you can find a 4-in-1 with 12v filtered output to the FC.

This frame kit favors a VTX with an off-center antenna connector. The "tail" plate that mounts to the back has a groove that can be fitted to the left or the right depending on how you orient your VTX. They also provide a plate to mount above the flight controller, but the standoffs are too short to raise it above the LED panel. If you've got taller standoffs you might want to raise the platform to sandwich the VTX between it and the top plate.
