How to limit ROLL ANGLE in AUTO mode?

Hi Guys

I want to control my roll angle in AUTO mode.
What is the parameter for it ??

There is no such feature, why would you do that ?
You are basically asking for “if wind is stronger, just let it blow away with the wind”

Sometimes in flight i have noticed Quad tilts to the left during flight which i think due to lipo battery displaces during flight . As a result the left side motors applies more power and quad takes extra battery.

So limiting the roll angle would make the Quad stable during flight .

Limiting the roll angle is not going to fix a physical weight and balance problem. That will just cause it to crash somewhere. It would be best to properly balance the copter, or just live with the battery consumption.
