Well, i am search for ppz altitude hold and found this videos:
i think this videos have made using old ppz booz hardware.
I never get any result like this.
anybody get a good alt_hold using bmp085 ?
i will continue my tests but i appreciate any help with config.
attached are the bmp085 capture.
As you can see the variation is about 2m.
i captured this inside home with all door and windows closed.
outside the graphic have much more peaks and the rotorcraft jump when peak occurs.
