I might be getting back into the R/C hobby soon, and when I do I want to buy a Traxxas 2.4GHZ system. I have to have 4 channels for the plans I have in store for my R/C. My question is, which system should I get? The "Traxxas Link" system looks too confusing and complicated for me. The "Spread Spectrum" system seems easier to deal with, but IDK the differences between the two. Could somebody explain the differences please? I've watched the videos and read up on them, but I'm stilll a little in the dark here. I would also like comments on how you like the radios. Thanks
