I have some terrible oscillation on my new setup mobi 130.
PID tuning, soft mount motor, soft mount FC, balancing props, tuning notch filters - does not help at all.
After soft mount motors and FC - it just became worse =)
Tried different PIDs during flight - lowering the P only makes it more "floating".
my setup:
motors - DYS1306-4000KV
FC and ESC - XJB F425 Dshot Flytower Micro F4 AIO OSD BEC Flight Controller & 25A Blheli_S 2-4S 4 In 1 ESC
frame - MOBI X3 (4mm plate)
RX - XM+
camera - Mobius Mini
