This is the 5th version of my lego crawler. The first version was build more then three years ago. I’ve used RC4WD Mud Slingers 1.9 Tires Soft on the current model.The main gear ratio is 12/20. The linear actuator is used in steering mechanism. It is not very powerful but it lets to make the front axel very simple and light. PFS XL motor is used for acceleration and PFS M motor for steering. Both motors are mounted on the chassis. The cabin is removable with lego mini figures inside.
