How would that work? I am considering dumping my DX3s for a 4ch Traxxas Link TX to have one for all my cars. I have a 2ch link already, and was going to program that to run them all too and give it to my gf to use on her stampede. If I do this, what do I do when we want to bash so that she doesn't end up controlling one of my machines instead of hers?
