i converted my LST to LST2 spec, and though the LST2 axles are 100% better than the earlier ones, I still bent, rebuilt, and replaced the axles a few times and that was with a nitroburner. With the LST axles it was broken pins all the time, with the LST2 axles it was making the holes bigger that the pin goes through. I like dogbones better, much simpler.
