My Arrma Nero makes a grinding sound and won't move any idea what it could be I'm new to the hobby
Start with the simple stuff like rocks in the pinion or jammed in one of the universals. Then, if it's a diff brain, make sure they are all unlocked and take the shafts off of the outdrives of each diff to see if you have a goobered up wheel bearing or differential. Once you determine where the problem is, tear it down and see what's going on.

There is a small pin (2mm wrench) that goes into a plastic collar on the end of each drive shaft. That's the part you need to remove to see what's grinding.
Thanks I took the truck apart and the gears in the center is missing some teeth once I replace that it should take care of the problem I just hope I can put the truck back together
