The deal is done and completed, the CS OT twin diesel arrived 1/2 an hour ago by EMS courier.
A little disappointed about the absence of any parts list or instructions whatsoever, however quite happy with the engine.
It will take me some time to get into the shed and sort a test stand for it, but this one is a keeper and a runner !
More later, but here's a link to the CS site info on the twin; http://www.csmodelengine.com/?a=product&id=16
