Oops [:'(]. Guilty as charged John. Freudian slip perhaps? Spelling (well, usage) corrected sir.

I am finding this Aurora engine intriguing. In my subjective evaluation well worth the $90- just for the "experience" alone! But it is by no means a "buy and fly" proposition. I could see how many R/C'ers would consider it junk. There is some nice workmanship in it, and there is some very, very ordinary stuff. It could, if assembled with care, and attention to fits, be an extremely competent twin ball raced traditional diesel.

It am thinking ... it would be nice to see Aurora consider an "export only" version of their line of diesel engines, assembled "clean", and made with more care for fits and tolerances. They could charge a little more for this. There is nothing fundamentally wrong with design of the engine I have. Just some poor hardware and lack of care in machining some areas. I'll expand on that last comment later.
