Not sure what the solution is though sure it is most likely something simple like changing a setting somewhere...

Heres the deal; when I go out to fly it starts up fine, headspeed spools right up, control is good. But after between 1 and 3 minutes of flying it will suddenly throttle down around 30-50%. Still keeps flying fine. If I land it will repeat the same process. Land again, repeat.. It does not throttle down to the level that it does when the batteries have reached their lower limit. Headspeed is high enough to fly around in other words and all other controls work as they should. Stability is good.

It was not doing this last week at all.

Everything is stock except for JR servos, CopterX metal head and tail, Helicommand and plastiblades.

Batteries are all 25C 2200mah LiPo's. All check out fine. In fact just to make sure I tried a brand new battery, freshly charged, and it did the same thing.

Swash plats level, blade pitch dead on, blades balanced.

Here are the settings in my DX6i, I am thinking this is where the issue lies though maybe it is the ESC?

Throtle Curves
-------------------------------------------
NORMAL
L: 0
2: 33.5
3: 50
4: 67.5
H: 100

THROTTLE UP/STUNT
L: 0
2: 33.5
3: 50
4: 67.5
H: 85

Pitch Curves
-------------------------------------------
NORMAL
L: 25
2: 40
3: 50
4: 75
H: 100

THROTTLE UP/STUNT
L: 40
2: 45
3: 50
4: 75
H: 100

The curves above are based on a mix of suggestions in the B400 Bible. Open to any suggestions.

I am not doing any 3D stuff/inverted or loops just yet. Just circles, figure 8's and some side in hovering. Keeping it to no more than 15-20 feet up.

Any help is appreciated!
