The Spektrum DSM Airtronics system will work with
the Super Exes radio but it has not been tested on the previous model. We do not
advocate the use of the Spektrum DSM with the Exes radio.
I hope you find this information useful, if you have any further questions or
concerns please feel free to contact us via email or phone
I would recommend to check part number of the existing Tx module of your exzess. If it is the same with the super exzess or M8, I would say it has a good chance. We have been using it with M8, M11 and super exzess, so I don't know exactly for the exzess.
