Nice car!!..
As I said, the two kits I bought had been sitting around in some Czech hobby-shop for easily three, maybe even four years.. So I never intended to suggest the DM-1 was flawed. Was just asking. And it seems like the answer is no, the DM-1 is not known to have diff issues.. I need to go check again, but a few minutes before it happened, I upped the brake bias a little on the radio to try to get more braking, so maybe I screwed something up.. Or maybe I had something else wrong in the linkage setup or something..
