Hmmm, 70mph. I am going to go out on a limb and say that you will need some power to do this. Finnster had his crt.5 going pretty fast, check his threads as I can't remember the name of it...

I will say that you will need a high quality motor to get that kind of speed and decent temps. I would say that a neu 1506 on 4s lipo spinning around 50k rpm would do it. You would need a 3500 kv motor to do that. The velineon motor will not be powerful enough to do 70mph. Not sure about the losi system, but I do not think it will either. Maybe a 4500kv neu on good 3s lipo batteries would do it, but that may be pushing it. A mm would be a good esc for this, but you would want to disable the internal bec and run a ccbec to keep temps down, plus this is mandatory if you want to run more than 3s in the mm (and good to do over 2s lipo IMO.)
