Yeah, I noticed it too.
Why put 2 holes in for the battery position and not motor position. ops.
I hope they do a rolling update on the chassis one day. I think we can manage to drill a 3mm hole in the side guard.
As mentioned the rear motor position is only used for really loose and blown out tracks and then you run it without the 4th screw (front, ESC tray and back)…….so not really an issue.
If you really want to run that last screw either drill a new 3mm hole (takes 30 seconds including countersinking it) or use a low profile nut instead of the standard one (or just Dremel it down).
