Time to update BF and tune with my 210mm race quad.
I held off updating right away when Betaflight 4 first came out. I'm very happy with my tune on 3.5.7 and was not in a rush to move to this new and very different version.
I've heard and read a lot about the new filters and changes to PID loop and other additions so will eventually need to get on it.
I left everything default, all filters and PID settings are BF 4.0.2 settings. The only changes I made were to the rates, and very minimal.
I lower RC rate just a bit, down to .9 on all axis. I also add .4 expo to all axis, including throttle and I also zero out throttle mid.

First thing I noticed was that the tune was much closer to how I like it right out of the box. PID settings are very close, and much of this can most likely be contributed to improved filtering and the addition of D_Min and I term relax. I notice that the I term default settings are much higher than in previous builds, especially yaw.
I ended up adding just a touch of P on all axis and backing off I term on yaw just a bit. Very, very close though without changing anything, and that seems to be what BF is going for.

Seems very nice, now the real test, take it to some events :)
going to be a great summer !!

Hope this video helps and comment with any questions.
