Thought I would share something that may be useful for others. I tried connecting my Devo 10 as a Slave to my Spektrum DX6 using the Spektrum wireless link and guess what.....it works. Absolutely chuffed, no wires dangling between my son and I.
Would be great if the developers could get Devation to Devation working such that a master Devo/Jumper can bind to a slave using DSM2/DSMX
