I experience altitude problems shortly after tackoff, the height can be ofside very extreme even up to + or - 200 meters, this happens with EK2_ALT_SOURCE baro and gps, but sometimes this can be normal, only when tackoff determines, if after normal tackoff then long flight will be normal until landing, maybe only 1-2 meters offside.
sorry I don’t have a log, because I’m still confused by how to download the log from my fc.
after some changes finally the problem was solved, my error made changes at once, and that made me not know what made the problem complete, I will mention some of the changes that I made to people who might experience the same problem.
-upgrade fw latest v3.9.8
-terrain-enable = 0
I am a little inclined to believe this is solved by the updated fw, but in Tridge’s writing in the FW release it does not reveal any changes related to the problem I experienced
