They are dogs in stock form. Sluggish off the line and lacking acceleration in general - especially compared to brushless beasts most guys around here run.
Personally, I think the baja would be quite an easy brushless conversion - and wouldn't require anything special in the way of a system. In fact, this vehicle would likely lose a couple pounds when making the conversion, and would draw less current than some of the 13 pound maxxes around here(the motor, pipe and fuel tank on these things are big and heavy). 6s Lipo with an xl or so motor and the baja should be under 15 pounds with all kinds of power. :)
