in my Octo APR in Coax configuration I made many test flights and all went well without problems
a few days ago I flew about 150 km from the test airfield and the Coax had a serious altitude problem. No Crash but after the first few minutes of flight he starts doing a yo-yo.
After an analysis of the log it is noted that 2 out of 3 barometers are perfect (BARO 2 and BARO 3) but one (BARO) is very different from the others
How do I solve it? … is it always better to adjust the pressure at each flight ?? (I hope not !!)
