I'm running with my DX6i. Initially had problems because I had the tx turned on, and the sim would not recognize it from the usb port. Turned off the tx and was there! Also was a little slow figuring out I had to highlight the tx tabs, especially the spectrum, all the way to the left of the bar. Took me awhile to figure that out. Even had to do the advanced setup for unrecognized tx. Played around a little before I found that only the far left of every bar is hot. Runs much better with spectrum and dx6i selected. Was cutting out at low rpm's with the unrecognized tx. Now it's smooth as silk. The cord that came with the program was the usb,box, and plugged directly into the trainer port. Best 129 ever spent. free shipping. bought after dinner on Sunday, simming before lunch on Thursday. I'm pretty happy with Mark Twain Hobby on ebay. Bought the realflight and pheonix from them. phoenix is more suited to what i need/want and runs on my laptop and desktop.....
