However with 17.5, I obviously need every drop of power I can get especially at my track. I understand all lipos will lose some punch while using them but like I said, mine seem to be losing quite a bit of punch. Do you think it's just because they're nanotechs or does this sound normal? Btw, they're only about a month old and they're very well balanced. No puffing or anything.
