You need to make a short, timed run on the track and see what goes back into the lipo. Then you can figure a mah/min and have a better idea on where you'll be after 6 - 7 min. From what I've seen, this usually turns out to be numbers like 120-150mah/min so I don't see where you'll have a prob. But I'd find out rather than taking any chances.
Use the money for something else.
Thanks Duster...the money saving is one thing but not adding any more weight, even a few grams is another. I will do some test runs after I get the lipo. I may decide to get a new ESC with a lipo cut-off eventually so I didn't want to buy something now that I may not use for a while.
