Kyoshos new crawler uses worm drives on the axles, the rear axle has a servo operated dig setup so you can have full drive, rear locked or rear freewheeling.
Expect to see it in the UK before the end of the year.
Using worm drives usually means you either have drive or it's locked, it's also useful to also be able to freewheel the back wheels on steep climbs, you use the front dig to stop the back end flipping the truck over while still freewheeling so the front end can pull the truck up. Braking the rear axle is used for extra tight steering and control on steep descents.
