Default The difference between regular and HV ESCs? Please explain...

Hello all..

I'm a little vague on the difference between a regular ESC and a High Voltage ESC.

Let's say I need to choose between the

the CC Phoenix 80 Amp ESC

and the CC Phoenix 85 Amp HV ESC:

http://www3.towerhobbies.com/cgi-bin...?&I=LXLBY4&P=M


There are few differences I see, the HV version looks to have heavier gauge power wires, and heat sinks...

But if I'm to run a motor (e-flite 60, rimfire 50-65-450, AXI 4130/20) that either ESC could handle, why would I spend the extra $$$ on the HV?

What does the HV version buy me?

What can I do with one, that I can't do with the other?

Like I said, maybe a naive question....

Thanks in advance....

I'm not a plane guy, but usually if one is staying below a certain voltage then either one would work, but if going over 25 volts the HV is in order.

I guess it depends on the voltage you desire to input.

For those motors you'd want the HV 45. That Axi for example on 9 cells (900 watts) is a great motor, on 12 cells (1200-1400 watts) it's as good as a hot .46 glow engine.
