It is hoped that the tracked chassis can have more health than the suspended chassis. Nowadays, the winning or losing of the competition can be said to depend on the number of suspended chassis.

The crawler chassis often needs to be sideways, and the exposed part is larger. Also, dictators are rarely used by players now.Advice from an old player
