RE: New OS 33cc Gasser..any reports yet?
I've got the OS GT33 engine, ES30G CF pipe and a home made Hyde clone isolator mount (similar to MTK's) on my EF 78" Extra. Mine is somewhat heavy at 13#. Awsome power. Tons of vertical. I'm now using the Biela 19-10 prop. I couldn't be happier. The OS tends to want to start backwards until you get the technique down. The engine has gobs of compression. The Mintor 38 did not want to swing this prop. I've had no problem hand starting the engine in 55F temperatures. I just need to make sure I get a good prime on it.
