It turned out to be a RX issue. I found I had another spektrum TX and tried it, and got it all to work, but am failing with my rx, which is odd, cos only a week ago it was working fine. Will have a look and see if I can work out what I've done.
But I've connected it to my 9XR and DX8. Only have the 9XR due to the club I'm with, hardly anyone with spektrum, but oh well...
It will go to the old man later, and use my spektrum for everything.

Once i've got a few landings under my belt with this thing, I'll put the rocket pods etc on it
