get a shift on - they've only got one left!
This TX is the same as I have under the German brand name of Reely!
I'm very happy with it and these sets were discussed on the site a few months ago under 'Tank steering'.
They TX and RX are bound on delivery, mine worked straight out of the box😊 So you should only need to bind TX and RX if you have changed one of them. Attached is the relevant page from my instruction manual. Cheers Doug 😎 PS "check the digital encoding ..." in the binding instruction simply means make sure both TX and RX have the same version of AFHDS! This is marked on the cases. I see from your pic yours and mine are both 2A.
