For what will come out of the box, yes, I guess you are correct. But I wonder if they will have a mount to put a bigger can in there? There are always the nuts out there that say "there's no such thing as too much power".
Talking to some guys at Hobbytown today about the 4x4 Slash and they stated there is a mount already out to put a MM in it. Wouldn't surprise me if the same thing could be done with this rig here. 1/10 BLs in 1/16 has been made standard for 2 well known traxxas products, who knows about this HPI 1/10 product.
