Great choice, Traxxas has parts support at just about any LHS and everywhere online. I'm getting the Monster Mutt for my daughter, I just have to figure out when.
It's a good truck for younger drivers. It's based on the Stampede so it's a proven platform. It does have the training mode which limit is to half throttle. And as said before, parts availability is great.
maby look at the 1/16 summit? For a few $ more you will have 4x4. I got the above my my girl but going to be going and getting the summit for her as she wants to drive in the spots i take my summit.. And for some reason my local shop had it for the same price as the above veh. So I'm hoping they will get more in
