BG101223145 I own a kraton 6s v3 and the lower and upper arms are swappable. I don’t own a hyper sst but my buddy does and they are basically the same frame very similar. I bought this to throw a castle 8s sensored system in and push its limits and he survived a crash when hydroplaning on a wet road at 70mph. Granted the upper arm and steering rod broke when crashing into a rim at 70mph I consider that pretty strong. Kratons are great for bashing no doubt but their arms are weak. My xmaxx is the only rc I think is ready to bash out the box. My kraton I replaced the arms with rpm arms before bashing.
