I've seen that page. Looking at the designs of Traxxas connecting rods, I can see where the weak points exist, but I still have to wonder what they're doing wrong to fracture connecting rods so often. I have never, in 8 years of running RTR nitro engines, broken a connecting rod. I have to chalk it up to Traxxas marketing their products to casual hobbyists who just want to drive RC cars fast, and aren't looking for the opportunity to develop significant skill in engine tuning.
