I couldnt help but share! I throw everything i could at my d413 tonight abd it took it! Take a wild guess at the things tht happened tonight and you would be right! Tumbled down the straight at full tilt, barrel rolled the triple, traction rolled down the step downs, lawn darted the triple and the only thing tht happend was a shock cap poppin off twice lol! And now tht i finally updated my v3.1... This thing flies! If u doubted the durability on this. Pm me lol its the real deal.
