MMM & Spektrum users, I require your council..

[BP-Revo]

Easiest way is to bind the Spektrum unit with a battery or BEC. Test it with a servo to make sure it's working.

Set your EPA's to max and calibrate it to the MMM.

The only thing is why are you using a DX6 and not a DX3 or DX3R? Isn't a DX6 a plane controller?
