Hello Bafangers. So looks like we have late Christmas. ;) New M560 revision is dead silent! Unbelievable. And finally new firmware v1.6 - can not tell now if some different behavior. I guess will be more lazy as bafang is doing it recently. And you know we do like sharp racing responses. :)

New silent Bafang M560! We have Christmas. ;) Have not opened it to check the gears. But I guess there must be some "nylon" gear. Also was noticing different sound when was on a bench.Finally new firmwar...

Just got one spare M620 controller and to my surprise it is FC2.0 version. Even more surprised, firmware is from 2023. Till now I saw only FC1.1 and a few FC1.0
Anybody is using this controller? Have you noticed some difference?
