I myself drive a Durango. I had driven Losi for a while, I enjoy the engineering of the DNX. Very responsive to subtle set up changes, a little goes a long way. Durability..has been remarkable for me. Over the course of an entire year, I had cracked the rear wing support and found a "hairline" crack in my A arm at the end of the season.
As mentioned for parts availability, now that they are owned by Great Planes, there is not ANY issue for parts.
