The Triscamp engine was designed and built by Robert Washburn, of Washington. Robert produced this tiny radial engine by gearing three .020 size engines into one crankcase. It measures about 3.4-inches in diameter, 2.5-inches long, and weighs only 6 ounces. It burns methanol with castor oil and scavenges oil from the exhaust to lubricate the internal gear assembly and propeller shaft. This model is serial number 4 of only 8 that he built, and it is dated 1981. Engine courtesy of Steve Satkiewicks, IL.
