A common problem with FG MT5 and other similar models is that the differential cover is made of thin aluminum which is easily damaged and due to rocks and other debris getting caught between the diff and the chassis. FG Modellsport has now released a new diff cover for your FG models. The flexible plastic material make impressing becomes hardly possible and rocks that do happen to damage the cover is easier to remove and the cover is much cheaper then aluminum or steel covers.
FG Modellsport has also created a diff key which is similar to our FG MT differential upgrade tutorial, the key helps prevent small rocks and other debris from even getting caught between the differential and chassis. The new FG diff key is also made of the same hard plastic material as the new FG diff!
