Just had a quick look on spektrums web site it says the dx2e is backwards compatable with dsm2.
But i read somewhere that the dx4s which i have once it has had a firmware update no longer binds to the orange recievers which is why i havent done mine. The question is yours being a later handset will it or wont it bind?
As i should imagine spektrum want you to buy there recievers at £35 a pop as apossed to orange at £8 a pop.
Do you know anyone that runs one you could try binding your handset to, to try if not it might be worth the £8 to try, if no joy then ebay to get your money back.
