Braking moves Pitch and roll

ArduCopter Copter 3.6
1

Im tuning my copter, and Im not clear what part of the tunning PID can help me to fix this. As you can see in the video (Loiter), when I move side to side, or front to back, when I release the stick, the drone keep moving and 1 or 2 seconds,and then, the drone brakes to get stady.

How can I do the drone do that brake as soon as I release the stick?

Thanks!

Have you tried PosHold flight mode?

Ive been trying to tune my copter like you describe and I found that I had better consistency with PosHold.

Here is some good info:

Edit: Also this (its been a while since ive looked at this in particular, my memory is slowly coming back now that im reading about it again, haha):

http://ardupilot.org/copter/docs/parameters.html#loit-brk-delay-loiter-brake-start-delay-in-seconds

LOIT_BRK_DELAY: Loiter brake start delay (in seconds)

Note: This parameter is for advanced users

Loiter brake start delay (in seconds)

Range Increment Units
0 - 2 0.1 seconds

http://ardupilot.org/copter/docs/parameters.html#loit-brk-accel-loiter-braking-acceleration

LOIT_BRK_ACCEL: Loiter braking acceleration

Note: This parameter is for advanced users

Loiter braking acceleration in cm/s/s. Higher values stop the copter more quickly when the stick is centered.

Range Increment Units
25 - 250 1 centimeters per square second

I have no idea what the default is - but start by checking LOIT_BRK_DELAY, then check LOIT_BRK_ACCEL

great!!! thats seems the solution! I will try it!

Thanks!!

I think loiter

The braking mode should be optimized

Try these
LOIT_ACC_MAX,600
LOIT_BRK_ACCEL,300
LOIT_BRK_DELAY,0.3
LOIT_BRK_JERK,300
