I too have the DX7, with three of the 7ch and 2 of the 6100 Rx and they both work flawless so far. I had one experience were it was my fault in the setup, where I under managed the ESC in an electric DF and was depended on the BEC for a power source. When I over loaded the ESC it shut down and I lost all control of the model. So it is really important how well you research your installation. Now since then I have a TAM Rafale and it flies great on the DX7 with no issues from the radio install, and I am in the process of setting up my Bae Hawk with the DX7. Now I can wait until 12X comes out.
