RE: used t-maxx 2.5 value?
Ebay is always a good thing for your situation.. I would say if it's in good shape you will fetch $250 or so. They started going down, but after the 3.3 release, the 2.5s are seeming to hold in that range. $200 low book in hard run shape (5/10), $275 high book for near perfect shape (8-9/10).
It had an aluminum flywheel stock, so I am assuming you mean a vented flywheel or something.
