hey guys, new to fpv, been flying for a couple of months.
i crashed into a puddle with my eachine wizard and fried 2 esc's and broke 2 motors.
so i replaced them with racestar 30a v2 esc's and emax rs2306 2400kv white edition motors.
after doing this i have mid throttle oscillations, at first i thought it was pids, but after changing them to every value possible i couldnt tune it out.
so far i have tried:
current specs on the quad:

cpu load 38%
i have read that rev6 gyro's are quite sensitive with noisy motors?
here is a vid of the flight:
it is a bit more dramatic through dvr
any help would be greatly appreciated, i think i have spent about 3 weeks now trying to figure this out, it doesnt help that i am still learning everything either

after doing this i have mid throttle oscillations, at first i thought it was pids, but after changing them to every value possible i couldnt tune it out.
so far i have tried:
- soft mounting fc
- soft mounting motors
- replaced a motor that had a crappy bearing (still oscillating)
- replaced props with various brands (still oscillates without props on)
- calibrating esc's (throttle up, plug in battery, throttle down)
- making sure everything is tight
- not overtightening emax motors bolt that holds the bell on
- tried lowering my p and then running 0 on i and d and it still oscillates.
- made sure there is no bolts touching the windings
- added a silicone pad for the battery to sit on so it doesnt move
- using tpa
- callibrating accelerometer
- change min throttle
current specs on the quad:
hardware
- NAZE32 6DOF REV6
- 1500mah 4s battery
- hq glassfibre 5x4x3 props
- emax rs2306 white editions
- racestar 30a v2 esc's
- runcam owl
- eachine tx801 vtx
- tbs triumph rhcp antenna
