Just a Few Questions

[maxair45]

I just remembered I saw some esc's at my lhs and they were like $40 and resembled a quark. I asked why they were so cheap and it was because they were for airplanes and they didn't have breaks. Well If the esc dosen't have breaks my car can't the breaks that are already on there do it? I don't see why not. The only problem is where the breaks is also where the throttle goes too(gas and break servo as I said before) so either I need a another channel or ???
Could making a y harness for the servo and the esc do the trick? How many channels can the M8 run?

Thanks for all your help guys.
