These are the kind of claims that confuse me. I just can't see where that kind of difference can really be had. I could see maybe the extra 5mph coming from the added efficiency of the voltage, but 5 mph and 2.5 times the runtime....
Too many variables to deduce anything. Is the overall query based on, "why all the hype over hv?" when your lv setups work fine?

IMO low voltage setups only work as well as they do now because all of the esc manufacturers have had time to work the bugs out. A simple oversight in gearing or maintenance can highlight the shortcomings in these setups and make them go poof.

Whether they are really more efficient or not in terms of usable mah, I believe, in the end will be negligible. However, the power flowing is used more efficiently as evidenced by component temperatures. The peace of mind of having cool components is enough reason for me to go hv. Ambient temp is way better than, "within acceptable temp range".
