my friend recently got a t1000, the body has really only had one roll so cant tell how well it will hold up but i did notice the rigidity/lack of flex of the body compared to my 5sc but out of the box it was really quite good, handling was spot one, good power, exhaust was a clone of this http://www.bigsquidrc.com/pictures/hpi_racing/full/baja_header.jpg after a few runs the servos both failed in a strange way, bolts began threading, an idiotic design of the rear lower shock mount, the bumper mount broke and the rear shocks have no rebound (once compressed they do not spring back to original position) and the fronts seem to have developed a less severe version of this.
The km radio box is different to hpi's slightly, there is no drainage hole on the bottom (so a hpi radio box wouldnt fit in his km) and the servo mount on the km radio box for the steering was too small (unlike a hpi ) for an aftermarket servo i had which was a real pain.
But definately get a killswitch no matter what
