OK, Having just read this whole thread, I ask: did I make a mistake in just buying an OS.61 FX 2-stroke for the new 4* 60 coming from Tower? My only experience with a 4-stroke is a SIG Rascal with a SAITO.72.

The plane flies great!!! But the 4* 60 is really my first low-wing.
Can always but the .61 in something else!!!
