RB Concepts C4 nitro engine first fire up in my Mugen MBX5T RB Concept C5 C6 RC GAS

This won of my ebay scores. I got three Italian Engines for $40. You can always see the level or precision and attention to detail in Italians engines. This thing has a 5.5mm venturi so it will make its power on the bottom end.
