Av8tor, hey, nothing wrong with a little monologue.

Actually, I'm very interested in your findings with this engine. I'd say you've got a fine engine there. Ran my Echo 25.4cc again today: 16x8 Dynathrust 8600rpm. Either the engine is starting to loosen up a bit, or the cold dry autumn air real packs a punch. Last time I ran it, it barely got above 8000rpm. I'm sure it'll do a little better with an APC 16x8 (more efficient prop). Zero modifications, other than CH Synchrospark ign. I also haven't done much tuning on it. I think these little Echos will really come alive with an 16x6, if their powerband is anything like the G-23/G-26. The only reason I don't want to try it is because of the noise it'll make at higher rpms.
