If your yikong yk4101 RC car or any other RC car is primarily used for smooth track driving or has a relatively flat road surface, it may not need to be armored. However, if you often play in the following situations, I personally recommend that you add armor:
1. Driving on sand, mud, rocks and other complex terrain, the chassis is vulnerable to impact and wear.
2. Intense racing: especially when driving at high speed, the car is more likely to collide with obstacles or fly up, chassis armor can effectively reduce the impact.
3. Extreme driving: If you like to do extreme actions, such as jumping, tumbling, etc., the armor can protect the chassis from damage caused by the fall.
