WT85 and WT80 are both traditional standard-sized servo motors with aluminum alloy casings, weighing 85g and 80g respectively. The WT85 is driven by a brushless motor, while the WT80 is driven by a coreless motor. Both have been specifically optimized for use in crawler vehicles, making them more suitable for such applications than traditional general-purpose models.
