Thanks all for the quick ID.

so now the second part of the question. I would consider that this engine is in good to excellent used condition. the guy i bought it from (pattern guy at our field) said that he had just got it back from YS Performance before he sold it to me. i put 20 flights on it (got help from the local pattern guys including Dave Snow for help on tuning) and then pulled it out of the plane.

What would be a fair price to list it here on RCU?? what does a new one cost (if they even make a "regular" FZ?

thanks in advance.
