ddraewwg I've never seen anyone mention this. The mount itself sucks but there's a replacement motor mount that integrates the center diff mount. The mount uses all chassis holes to secure it very tightly. I have recommended that mod to many BX-8E owners and they have had no problems whatsoever.

ddraewwg Yes there is a manual with detailed views of major sections of the car such as the front and rear suspension, front and rear arms and then an exploded view of the entire car. also lists all the parts packages but Banggood doesn't stock all. Hard to get replacement screws but they are all sizes M3-M4 with varying lengths. Looks like a set of grub screws are M5's. Probably easier to get from Amazon...but as long as you get the right size and type, you should be fine.
