I am looking to get an upgrade from my DX6i and do not want to spend more than $200. what would be a good upgrade with more functionality?
is the taranis qx7 compatible with all spektrum receivers including the umx planes?
I need a new one for more model memory as well as 3 position switches for things like dual rates and flaps. The ability for the radio to talk to me and tell me how much time i have left will also be very helpful to me at the field so i don't have to look down to see how much time i have left
Out of the box, No, but the radio accepts external TX modules which can. Your budget is enough that you can fit in a Taranis QX7 and a irangex module.
One word of caution -- the Taranis series radios are arguably equal-or-better than the Spektrum radios in all but one way -- user friendliness. With a Spektrum radio, setup is simple. With the FRSky radios . . . well, it's gotten better, but still, it's rarely that. keep in mind, though, you're trading ease of use for horsepower -- while setup and tweaking the program may be more complicated, it is predictable and far more expandable. The OpenTX architecture it's built on is designed to let you do practically anything you might want to do, where Spektrum has programmed theirs to do what it expects you want easy . . . which is fine until you want to do something it doesn't expect and it becomes really hard (the latest versions are better, but the DX6i was bad about this).
So, if you're thinking about expanding what you're doing to the unusual, might be better to use this opportunity to struggle up the learning curve and move over to openTX, because you'll probably want to later. If you're not, the DX8e is a fine radio.
Using the Spektrum module using open transmitter with DSMX receivers don`t you have to rebind each time you change planes?
