So I got this little quad years ago as an rtf kit.

Upgraded the remote to a jumper t lite elrs and goggles to the eachine ev100.

I wanted to put a micro ceramic antenna elrs reciever on it but managed to tear the rx2 pad on the board.

So I decided to upgrade the whole aio board.

I went with the happymodel x12 elrs.
It has 12A esc and a 400mW vtx, big improovement.

Had to drill some holes on the frame to make it fit and I had to switch the black and yellow connectors on the camera lead to get video.
I desoldered the moror connentors and soldered the motor wires to the exposed pads.

Put the hq-prop 2.5x2x3v2s (basically 2.5 inches diameter and 2 inches of pitch).

I'm running the betaflight 4.3 stock pid tune.

In conclusion it is small and quiet but will rip any park.

UPDATE:
The aio flight controller got fried after sitting in a bush for half an hour.
I would recommend putting the "low power disarm" setting to "on" instead of "on until first arm" if you don't plan on going really far.
Since it was blasting 400mW the whole time it caused the board to overheat.

Expect a 3 inch freestyle build coming in a few months :)
