If I had it to do over again, I'd probably spend the extra dough and get the HPI one or spend a little less to get the duratrax deluxe bag due to the shoulder strap. That's the only gripe I have about mine... no shoulder strap.
But, the maxx, savage, 21 chassis maxx, Aftershock, LST2 all fit inside pretty well. The LST2 with stock tires is a bit wide, but it still fits.
