Basically, once you get the tranny "beefed" up and some good wheels that will take abuse...the Evader line is a great RC vehicle to have. I've gone from wanting to smash my Evader ST, to me never wanting to get rid of it (until parts supply runs out). It's a low maintenance RC for me. In general, a handful of bearings (I run in extreme dust) and possibly a new set or rear tires are needed every year.
