"Honestly nobody ideas ? Is there someone who could take a look at the logfile ? This behavior is strange.. I verifiesd it in multiple flights now. The sonar altiitude matches the baro, but sonar desired alt does not change ! What is wrong ?"
"Hi Will,
i dont think that you could pick much better motors than the U8. The vibrations you experienced are very likely caused by insufficient balancing of the props. Or you bought used motors that have been crashed and have a bended shaft…"

"Hi Gregor,
yes I did... the sonar is mounted on foam, shielded with a can and I also used the capacitors as suggested in the maxbotix article. As you can see in the log, the values seem to be correct. However I wonder why the copter reacts…"

"Hi,

"Hi Will,
probably your charger had a bad day counting the amps... i would try again. If this occurs regularly it can only be explained by
1. A difference in capacity of one battery -> the 8000mah one has lost 8000mah in capacity
2. A difference in…"

Hi Forums,I attached a Maxbotix 1240 sonar to my pixhawk and it works good so far. All testings on my desk show correct sonar values. However while flying in alt hold I can use sonar to rise by standing simply underneath it but then it wont descend…
