New receiver for free!!!

[ste_lazzaro]

Hi everybody!
I am posting here rather than in the trade section as I am not actually selling anything.
I bought an Orange receiver GR300R some time back.

(https://hobbyking.com/en_us/orangerx...-receiver.html)

I wanted to check whether it is compatible with my Spektrum DX3R transmitter, and found out it is not (despite some people saying it is...
So now I don't know what to do with it.
I would be happy to give it for free if anyone knows about compatibility.. I would only ask for the shipping cost (probably around a quid within the UK).

Let me know if interested!
Cheers
