Without trying to slam the Mi3.5. You won't achieve 1500g on it running cells, Are you saying that 1500g was too low a limit for Nimh? No you're not, so why are you so bothered with the new lower limit?
EVERY other top end chassis on the market will make 1350g. and even if they can only make 1370g, that's what I'll be running my car at anyway just to be safe.
