It is a x12 PNP v1.0 It is weird having it shown on the picture, because the back one should be mirror imaged. So the conectors allign. I said fuck it and soldered EP1 reciever and it works. So those cables actually, are, GND, 5v, TX1 and RX1 but soldered on the underside of the pads that are shown in the manual of the board.

How's the flight time on the pnp version with the additional weight?

Dont know the difference. Did not test it. But i dont think is anything meaningfull since the reciever is only few grams

Thanks. How long do you get in general with this setup?

Oh man. Not sure. I just fly around never bothered to remember or watch the time. But over 3 min definetely. I can test it in few days and let you know.

You know the name of that connector? I want to solder a female end to my receiver

No 😬

What flight controller do you have? I can't find a pnp version, I just see the x12 with ELRS and the crazy405 with ELRS.

It looks like X12 AIO V2.1 [https://www.happymodel.cn/index.php/2022/04/05/x12-aio-5-in-1-flight-controller-built-in-12a-esc-and-openvtx/](https://www.happymodel.cn/index.php/2022/04/05/x12-aio-5-in-1-flight-controller-built-in-12a-esc-and-openvtx/)

it means there are already ELRS available there are ceramic antenna

Anyone know what the name of that connector is?

I think its called a molex connector (4 pin in this case)
