Evolution .60 NX: There has been som reviews about this engine and reports say that the stock muffler is a real power killer, but the engine responds extremely well to the red Jett muffler and can then compete with the best of them (almost)

See the last post in this thread: http://www.rcuniverse.com/forum/m_91..._3/key_/tm.htm

The .61 NX is the older, heavier version of the .60 nx, it`s easy to mix them since the are almost named the same.


I`m really considering the .60 nx myself, 15200 rpm on APC 10-8 with the red Jett muffler is great. I wonder what it will do on APC 10-6 then?? The Jett .56 is said to turn that prop at 18000 rpm.
