Hi, I was facing something similar sometime ago before I put in a slipper. I ran the brand new db01 with a hot BL motor on high grip carpet (just looking if it really worked all right

) But while accelerating or braking there were some evil noises- I got strongly advised by the local experts to give it a rest ! On that highy grip carpet, the eccessive power "wouldnīt find any way out" but slipping both diffs !
They hadnīt started melting yet, but were hot and bruised (still working though...

)
So again: my own fault ! And again: been lucky !
was that of any help ?
