Yes, the Hitec Spectra 2.4Ghz module is compatible with any Futaba radio that uses the same size module. Also be aware that we offer the standard module (wired antenna that replaces the standard antenna in the same mounting location) with (2) 7Ch RX's for $129.99. However, the "Promo" module will be better if you plan to switch back and forth between 2.4Ghz and 72Mhz because the antenna is hard mounted onto the back of the module. But I guess if you send in your only 72Mhz module you won't be doing that now, will you?!?!?
