Coarse movement of the servos when in Stabilize Mode

Hello all.

1st of all, Thanks to all the people that participate and improve the Ardupilot project.

I have tried all the code posted since 2.0 and in all the versions I try, I found that when in mode MANUAL the servos movement are fluid and continuous   following the movement of the sticks in the radio.

But when I select the Stabilize mode, the movement of the servos due to the input of the arduimu (or the IR sensor) is fluid and smooth, but if I input some command using the Tx sticks, then the servos movement become  coarse and jumpy and sometimes doesn't reflect the stick position.

This is true also for channer3 (motor) and I already change the wire from pin 13 to pin 11 (and  change also the pin# in the code)

Did this happen also with your setups, jerky movements of the servos following your inputs in the Rc Tx but smooth movement following arduimu/ir sensor corrections??

How this reflects when the model is in the air flying?

    I think most of what you are seeing is due to the radio input filter. Due to the way we capture the input signals we apply some fairly heavy filtering. This seems to be necessary for some radio types but not for others. We left it in pretty heavy - better slow response than glitchy. If you want to see how it behaves for you with less filtering look in radio.pde. There are some comments in there that would help you change the filtering.
