I already have calibrated all the ESC with the receiver.

I don't think that is FFIMU ?
If that is everything defined in ConfigH theres your problem.
PM me if you still need help.

I'm new to MWC. Have had my stuff about a week. Here are the steps I took to get my tricopter to hover stable in my living room. Keep in mind im new.

1.) Did throttle range calibration on ESC
2.) Flashed unit to 2.3
3.) Did the esc calibration with ESC_CALIB_CANNOT_FLY in config.h
4.) Trimmed copter in acro mode / No mode
5.) calibrated ACC
6.) Did Take off and land Stick calibration to finish it off.

Hovers perfect

I did play around with the pids but stock work fine.

I have that board in one of my quads, #define FFIMUv2 is the right setting for it.

Have you balanced your props and mounted the Flight controller boards on some foam?

It looks like vibration problems I had early on, I couldn't tell from your video but I had a twitching servo on my tricopter, it still flew ok but was annoying.

To fix the twitch I used a higher refresh rate, #define SERVO_RFR_300HZ, but read the warnings about analog servos.
