Stable mode problem

[bear]

Hi all,
My quadX is using ADXL345 accelerometer with V1.9 code. I can takeoff it in acro mode.
But when I takeing off it in stable mode. Only the front or back side takeoff from ground.

Anybody have any ideas?

Many thanks for any assistance you can give.

Did you follow these steps?

1. Accelerometer (Acc) Calibration

2. Accelerometer (Acc) Trimming

Yes I was follow the ACC calibration and trimming steps. But I cannot sure ACC trimming is good.
