I mostly run 2wd stock off-road with my Losi XXX-BK2.. brushed and I can go well over 10 min if I wanted to on my Orion 3200.. but you can do that with a 4200mah NiMh too..
On a bench test my 3200 Orion can go 9min 38sec on a full 20amp constant load to 6v cutoff.. that is basically like a 27-turn brushed stock motor at full speed the whole time... we don't use full speed the whole time in a race..
There are guys at our track that have run both qualifying heats of 5min each and their 6min main on 1 charge! They aren't the guys that are winning.. but it's still kinda cool.
