RE: Hitec Spectra 2.4 module upgrade
Gerard, I got one of the sets with 2 receivers and a module from Tower Hobbies for a fair price and I'm using it in my 9c Futaba. My flying buddy has the older 8U and the module works great in it too. I would like one of the Promo modules but I don't have another module I am willing to part with right now.
