All as Mick said!
The only down side to the MX-22 is if you use a trainer system for buddy box. The MX-22 does not have this as a standard feature.
As with many of Graupner's radios its a plug in module, which uses fibre optics for the lead, so it is not directly compatable with std JR radio-you need a special RF module to go in a JR tx.
Other than that it has more features than a 10x, plus 30 model memories.
There will be plenty at CJ tomorrow.
