I tried but my computer does not even give me an option to install a com port. I tried to follow the instructions in this forum but couldn't get past #2 Maybe I didn't let it search long enough. I may try again. Thanks for the info.
Also I just bought the Flysky USB cable from Helipal and could not get it to work. So I went to Radioshack and bought a cable with a mono jack on both ends, downloaded Smartpropo and pluged it into the mic port and now I can use my DX7s and it works great with the beta 7.
