250 Quad with Pixfalcon help

Hi,

I converted my ZMR250 from a Naze 32 to a Pixfalcon. I got everything setup and vibrations looks fine.

I then did a auto-tune on the Roll axis and would like to know if it is normal for a small quad or should I be concerned with the low values.

Stabilize Roll = 4,873756

Roll P = 0,03859347

Roll I = 0,03859347

Roll D = 0,001254361

Imax = 0,444

Filt = 20,000

Firmware Ver. 3.4.6

I did try to auto-tune the Pitch axes as well. But the quad just fell out of the air close to the end of the cycle because of a dodgy battery.

I got new batteries and would like to attempt autotune again. I just need some reassurance.

Henry

  • Hi Henry,

    thanks to yours post here, I see the exact same problem I have!

    I suggest you to join the ardupilot community on the new forum at https://discuss.ardupilot.org/

    Please remake this post there and I'll join it with my same experience, I need to fix it too asap :) ...with no wind the little quad its perfectly stable, but as soon as a little breeze comes in its going drunk and not stable anymore :(

    Lets work on it Arducopter for little quad!

  • Hi I upgraded to Ver 3.5

    Here is a flight log if someone can look at it and point out problem areas please.

    Did not use autotune. I used PID's that flew OK and based on other users settings. I flies ok but seems that the slightest wind make it twitch. In no wind it is very stable

  • No 250 pilots out there????!!!!!!!

    I am a bit worried because it can not be set that low under Extended Configuration. You can do it under the full parameter settings but you get a warning that it is out of range.
