You may need to explain a little more about what you are asking. I have an M8 W/Spektrum and all that you do is take the original module out and install the Spektrum module. You don't have to get a new case. If this is not what you are asking, I appoligize.
Oh, my bad, sorry about that. I have a pocket in my sportwerks bag that i take the module out and put it in there along with the antennas. With my carpet cars, I run regular 75mhz so I cant get rid of the stock antenna.
