I have two Burns that have been run to death and back. I upgraded one with all the Turbo parts except the counter sunk chasis. They have brought many hours of pleasure to my RC life. I still run them, along with a USA-1 Nitro and a Kanai 3. I stocked up on all the parts that break before they stopped making them, so I will run them for a few more years, just bought a new engine for one of them.
I also have a USA-1 Nitro in the box along with a few upgrades.
