OK Cub .049b- my first engine,followed by a fox .29 my first "big" engine. I still have the Fox but the cub flew away to free flight heaven many years ago.

More recent standouts are a Super Tigre G60 Blue head which is Italy non-demanding. Another favorite is the OS 1.08 I have on my Lazy Ace. It is the old one without that stupid remote.NV. It almost never fails to start on the first flip, Just turn it over once to feel the "bump" then give it a flip. I don't use a chicken stick, it feels too awkward. Maybe it is a sign of my age, I fiddled with these things for many years before starters & chicken sticks came along.
