AQ6 lazy at PosHold-Mode, M4 too sensitive - how to fix ?

Hi folks,

have question about control behaviour in PosHold-Mode and how to change it.

My AQ6 ( 700-size X8 ) is pleasant in normal flight mode, but in PosHold-mode, i need to give very large stick-inputs to get him moving, while my M4 ( 550-size Quad ) is real aggressive in PosHold ( also pleasant in normal mode ). At the M4, i only need to give a real small stick input and it runs aggressive on roll and tilt, and this seems to lead also in short oscillations when releasing the sticks again.

Now i´m a little confused how to get rid of this problem. Need my x8 a little more agile and my M4 more cosy in PosHold-mode.

Both are running with PIDs, not at Quatos.

Any help is highly appreciated

There is a setting that will change how fast an Autoquad flight controller will let your copters fly in Position Hold.

There is also PID settings that can change how aggressive you copter will tilt.

You should post your parameters for both aircraft to get some answers.

sorry for late reply, was too busy to do earlier.

Attached are the params-files from both copters. Would be great if anybody could help me with my issues.

In general, the NAV parameters affect how your copters will fly in Position hold.

CTRL Parameters determine how copters fly in Stabilised flight and you seem to be happy with the way the CTRL parameters are working.

Your X8 maybe help by changing the NAV SPEED parameters. You must be using have a custom firmware that has the NAV SPEED parameters set so you have slow tilt rates.

NAV_POLYFENCE 0
NAV_SIMPLEFENCE 400

Changing to a more standard firmware will likely give you normal Position hold control.

If you lower the NAV_MAX_SPEED from 20 to 5 on your quad you should see a more reasonable response in a NAV mode.
