Troy,
I think you misunderstood what I was saying. Flying the heli the previous day and the tuning for the top end was ok. The next day of flying it was lean on the top end without changing any of the settings, not that the engine was lean on start up. Today the heli was richened and the glow pulg replaced, but it had no power and headspeed was down. I find it hard to believe that this is just a tuning issue, two of us have been working on this heli for the last 12 flights with no avail. It has been a most dissappointing experience so far.
