This engine was made in the U.S. by 77 Products using a British Merco 61 crankcase and innards. The polished head is the main difference from the standard engine, plus the lovely blue paintwork and spark ignition conversion (which looks to be the same as the Otto Bernhardt conversions). It has a Perry Carburetor and NGK spark plug. (Description provided by Peter Scott.) Joe Bridi donated a portion of his engine collection, along with some R/C aircraft, in July 2012.
Mr. Bridi is a long-time champion R/C aircraft flyer. At one time he had a collection of over 600 model engines. Many have since been sold, but he has donated some unusual and prototype engines that he flew in competition over the years. The museum also displays some of Joe’s R/C aircraft, featuring examples of some of his most popular kits. Most were his trade show display models. Our thanks to Joe Bridi for his contribution.
