The truck is nice and very stable and powerful with dual motors on each axle but the steering knuckles are plastic and will break with any serious crawling. You can use the ST Racing Concepts STA80004G Aluminum Steering Knuckles for The Axial AX10 as replacements. We replaced all four knuckles so if we want to add the rear steering servo in the future we won't have to deal with broken knuckles on the rear. Front and Rear are the same. One other thing that takes away from 5 stars is that the 3mm screws are just threaded into the plastic mounting holes cutting their own threads so when you remove the screws sometimes you take out the threads with them. Too bad the factory did not pre thread the holes. So consider a 3mm Tap and 3mm helicoil repair kit if you plan on any modifications.
