This updated engine has dual-valves and now delivers an honest 10lbs of thrust. I've added some extra ducting to the internals to help with airflow but seem to have over-done it. Now there's too much ram-effect which forces the engine to run lean once it gets flying-speed up. This was a short flight because once it became apparent that the engine was running lean I opted to cut and land (it was a blustery turbulent day). You can see that this engine has a *lot* of thrust by the way it "kicks" when it first starts and the amount of acceleration it has when released.
I reckon that the next flight will be "perfect".
Stay tuned -- it's summer here, the next flight won't be more than a week away.
