Well, I just thought it would be appropriate to comment on my experience with my purchase from MECOA.
All I can say is "WOW". The engines I bought (HP .61 and Fox .35) are absolutely beautiful. The HP came with a beautiful box and all the normal supplies that would be expected if this engine was purchased from the original maker: muffler with the required mounting screws and allen key, the proper foam padding in the box and all the correct documentation. The Fox engine came with a beautiful repro of the original running instructions.
Plus, the delivery included a nice MECOA hat.
The ngines are absolutely beautiful. If they run even half as good as they look, then I will be more than satisfied.
