SG116 / SCY 16101: repair locked differentials on factory-fresh car

Fix applies to these models, which are all the same chassis: Teeggi/ZLL SG116 Beast; SCY Conquer 16101 / 16102 / 16103 / 16201; Amewi 22605 Conquer Race Truggy This wasn't the first SCY car I've had where both differentials were locked up after I unboxed it. To drive corners, the opposite wheels must be able to rotate freely in opposite directions. That’s exactly what differentials were invented for. In this video, I take apart a brand-new, just-unboxed car, demonstrate the problem, and perform the repair: You have to loosen the 4 screws on each differential. They were tightened WAY too tightly at the factory. I also wanted to install new shocks, but ran into a problem: The new lower bushings where too wide to fit onto the arm. Off-camera I took the lower bushing of all the shocks and put the stock bushing in the new shocks.
