Hi to all of you,
I am new to R/C Universe forums and just now getting back into R/C flying.  I want to upgrade my Futaba 8ch radio to 2.4 GHz and I also saw the add in Model Aviation  offered by Hitec.  In the short add it stated the Hitec Spectra 2.4 module would also be available to owners of Futaba radios, just send in your Futaba-TP-FM 72 MHz Module plus $19.95 + $5 S&H.  My question is this, is the Hitec Spectra 2.4 Module Upgrade truly interchangeable between both Futaba and Hitec radios? Both modules of the same size and pin configuration?  Good questions to know before
committing to add and sending in your 72 MHz Module!  Any unforeseen problems? Any help with this would be greatly appreciated. Thanks.
