In February work started on a third design, the W.1A, which was the size of the W.1 but used the W.2's mechanical layout.
The main reason for the increase in length, however, was the planned change in the mechanical layout of these ships.
The mechanical layout was as before except for the deletion of the 1.85-litre engine.
Most of the chassis construction was the same, as well as the mechanical layout.
The more pressing concern was the mechanical layout of the grid.
The larger Volkswagen Type 4 was introduced in 1968 which had a similar mechanical layout with further engineering refinements.
This mechanical layout is intended to give optimal weight distribution (25% at each wheel) with driver onboard.
Note the very simple mechanical layout.
I've got all the details of the ParaSyn campus, including plans of the labs, mechanical layouts, the works.
The V4s had similarities in their appearance and mechanical layout to the V2 "Green Arrow" class.
