Ah, I see. Well I had the opposite proplem as you with that engine. Is it a different brand fuel as well? I had 15% os band X and couldn't get the thing to run worth crap, and was dead stick every flight. Switched to Cool Power 15% Heli fuel and it runs perfect now. Never adjust it and it never dies. Sounds like you already know how to adjust it so maybe try a different fuel.

Edit: My mistake. I thought you said you changed fuel. No clue where I got that idea from.
