ph2t: will you be using li-ion/li-polys or 4 cells ni-mh? i think that the pro-pan chassis is ideal for using li-poly/li-ion and the pro-stock chassis with pro-mod upgrade is ideal for 4cell AAA batteries but you can fit li-polys under the upper deck if they were small enough. both chassis hold aftermarket electronics if their small enough.the only difference is that the pro-stock with pro-mod has an upper deck/brace that can hold the batteries down so that they are interchangeable but the pro-pan chassis is just a pan chassis where you have to double-sided tape everything to stay.
i hope this clears a few things up.
