Yes the XP is 72mhz. The X9303 is the 2.4 integrated version.
The xp model has a removable module in the back and you can get the Spektrum 2.4 conversion module from Horizon to convert it to 2.4 but I doubt it will bind with that particular helicopter. The receiver has to be DSM2 compatable to bind with a Spektrum module.
