I researched for about a year, and the only difference between the HPI and the KM car that I could find is the price! Before even starting my car, I bought a bunch of parts for the HPI off of ebay and installed them on my KM t1000, and they all fit perfectly. The motor seems fine to me. It has a LOT of power! Again, I've lurked on the Hpi forums for a year, and they have the same short comings as the KM brand. Everyone universally agrees that the stock plastic clutch carrier is crap! And the Turtle Racing enclosed system is the best fix for it. A friend of mine got the Baja 5T, and I just couldn't run my Nitro car anymore! I got mine from ebay. Heat hobby, I believe. Danlc4 is another great ebay'er, but I don't think he has any t1000's right now.
