Mulitwii Crius 450 quad Oscillating

Post by joystix2 »

Im getting the oscillation of death when I come down in altitude at even a decent rate of speed. I have attached my Multiwii settings. Can you guys take a look and give me some feedback on what I could try and change to get rid of the bad oscillation? Thanks in advance

Try to set LPF filter 42Hz for your gyro in config.h file and remember to increase PID's a little.

MINTHROTTLE too low? When copter armed do the motors stop with throttle at idle and any input from yaw, pitch or roll? If so, FC can´t stabilize the copter in a situation you described, just because it needs the motors running.

Try to increase MINTHROTTLE (don´t forget to clear EEPROM prior to that, otherwise the old settings remain) until all props keep turning at idle with simultaneous steering input.

Regards, Philipp
