I never knew the TQI did that, so typically, when i get them, i give them away, since i already had a Fly Sky FS-GT3B.There are quite a few aftermarket radios that have multi model memory but the TQi is the only ready to run system that I know of that does. I've had a few of the lower end Flyskys over the years, pretty decent radios. I was tempted to get a Nobile but I ended up getting a Radiolink RCG6S V2 for Christmas. So far I like it better than the DX5C other than the need for 6 batteries and the antenna. If they could get it to 4 aa and get rid of the collapsible antenna it would be even better.
