Is the MN MODEL MN38 RC CAR differential made of metal?

As a key component in the transmission system of the remote control car, the differential needs to withstand large torque and speed changes, so its material selection needs to have sufficient strength and wear resistance. Metal, especially high-strength materials such as high-quality alloy steel or carbon steel, is an ideal choice for manufacturing key components such as differential gears and shafts. These materials can provide sufficient strength and support performance to ensure that the differential maintains stability and reliability under high-speed operation and complex road conditions.
