Its 2WD. Unfortunately, that truck, from what i understand, isnt available anymore. You can still get the brushed version, last i checked, but the brushless 3S version hasnt been available for a few months now.
This is just a video i made of me running my 3S Losi 22s at a local place where the highway department dumps gravel and asphalt from road projects:
The video is a bit dark at times due to the cheap action cameras i use, so i apologize for that.
