Could you not state anything more obvious, I don't have any problem with the basics but thank you for caring.
I asked the question as it would be cheaper to buy a 2.4GHZ Futaba system than to buy the tranny and Spektrum module for it separate. I asked it because I have about 4 Spektrum Pro receivers for my current KO Universe & Spektrum.
I'll be getting a 3VCS (hopefully with no module if possible - will see), then a Spektrum Pro module for it, so I can use all my receivers.
OR, I may sell all the Spektrum stuff I have, and use the Futaba 2.4Ghz module, with the right Futaba receivers.
