This Profi water-cooled V-twin engine display was put together by Dr. Bob Kradjian, of CA, in 2001. This is an early water-cooled Profi V-twin (circa 2000) that burns methanol on glow ignition, with castor oil mixed in for lubrication. The engine was very limited in production and immediately became a must-have for model engine collectors. Dr. Bob Kradjian is an accomplished machinist and a professional when it comes to exhibits. He added his expertly machined and beautifully polished engine mount and fuel tank to augment this very pleasing display.
