i have read through the comments, seen the pic's and watched the video's. there was never a clip. aluminum grinding down a weld is absolutely possible. i have used a upper and lower clip in every motor i have ever built. overkill? yeah probably, but why pull more on one side (bottom) than the other? anyone that thinks this is fishy is crazy. clear cut... tyson got side tracked and simply forgot the clip. to me this falls under workmanship and should replace any and everything affected.
