Thanks Rivetcounter, Tanque, & Maus45, I REALLY appreciate (and NEED) the advice. When I get the motors in and start the rough wiring I'll try both ways. But remember, I hardly know anything about electronics. Just how to plug things in.
I'll have get a couple of Sabertooths for it like in my tanks... on the Sabertooths there's tiny levers to initially set'em up and I'm pretty sure there's one (or two) for 'mixing'. I'll find the instructions and check on that.
AND one of these extra radios I have (the 7 ch. that came with the Panther and I never figured out) does have 'mixing' on one of the display screens. But I don't know how to program it...
And Tanque, I'll look for a Y receiver cable on Hobby King and see what they got. And a turngy v-mix? What is that Maus?
Thanks again for the help!!!!! Mike
