Since i got into this method of transport/hobby 4 1/2 years ago, all of the engines and replacement crankshafts purchased from my vendor have only used the design as shown on the left hand side of the photo.
The biggest improvement to reliability has been the adoption of crowded needle roller "big end" bearing design; also known as a full compliment bearing design.
