Does anyone have this engine? how does it compare to other 26cc engines?

There's already a thread discussing about xyz engines. Pls take a look here: http://www.rcuniverse.com/forum/m_7162422/tm.htm

I was looking at the XYZ but ended up going with the crrc because there seemed to be more positive feedback on it. I have not run it yet so I can't personally say how it runs.
