I am hoping that someone has had this problem and can help me out. I have a Carbon Cub S+ that was RTF, I wanted to bind my DX8 and went thru the procedure and I just could not make it work.
I went bask to the Spectrum transmitter that came with the package and now I can't get it to bind.
I have tried inside, outside, in the middle of a field and I can't sort this out. Any help would be great, thanks.

I have a Sport Cub S that I had trouble binding with my DX6 a couple times. Once I was too close to the airplane and after I backed up a few more feet it bound ok. Another time I think it was the power up sequence. Rx first then Tx or vice versa. Try these if you haven`t already. You could also try the Radios, Receivers Mfr.
