250 Quad with Pixfalcon autotune help

Posted by Henry Scheun on July 21, 2017 at 12:02am

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.

    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.

    Thanks for your reply.

    I was 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.

    I will try the autotune again this weekend and report back.

    Thanks again.

    Henry

    Those seem OK, proof will be in the flying. How does it feel?
