I currently own a the (4908) and I'm trying to find parts for it online and I've noticed that most of the websites don't clearly tell you which parts will fit on the newest maxx. They say "fits 2.5/ 3.3" but not which 3.3, this leads me to believe that either I'm a "Big Dummy" or that these guys are just lazy!! Now I'm ready to accept the fact that I'm an idiot so can anyone help the slow guy (me) which parts are interchangable? thanx:\
