OK 2 minutes is not so far from my 45 second exagerated guess. Yes more than double but it's not what I'd consider a realistic run time unless you are talking about a shuttle launch, top fuel run or some sort of cool pyrotechnic display. I didn't realize that BT was running lipo (I saw "6 cell" and assuemed 6 cell packs, I have no experience with Lipos. I can't imagine draining 4200mah (nimh) out of a battery in less than 3 minutes w/o it being white hot. I prop up to 45mm and run for 5 minutes and risk poaching my IB's How is this made possible, Dude.
