I'm settig up a Trex 600EFL Pro with 3GX V.3 with 2 DSM2 sats. with a DX7. After binding and getting into dir mode once and doing system initial setup, I went to go back and finish and it wont let me go into dir again. Tried rebinding, reloading software and firmware, everything I could think of and still no go. Any thoughts out there? I've just reset the DX7 and created a new model, and deleted the old software on my computer and installed V.3 again for the 3rd time, and it binds up but just wont go to dir mode!
