I had one about ten years ago. It turned out to be a really strong, reliable engine. Being an Enya fan, I wasn't surprised.

The 80-4C is really a .74 and is built in a 60-4C frame. It is compact for the power it produces.

I mounted mine on a CGM Anniversary Cub that weighed over 7 lbs. I could perform climbing knife-edge flight and Immelmann right from a short take-off roll. That is one strong engine. Mine never quit until I made it quit.
