RE: Hitec Spectra 2.4 module upgrade
I know of 3 members of my club that are using Hitec 72Mhz modules in the Futaba transmitters without problems.
I know the pin out for each module is the same and they look identical on the outside.
Now will the 2.4Ghz work, dont know for sure but if the others work I would have to believe it will work with Futaba
