Me and a buddy bought xl5's yesterday, built a small track, and we have already burnt through 2 motors! we were letting them cool down between runs, but in honesty running them pretty hard while we where hitting the track, i assumed they could hold up to it but no luck, i dont want to upgrade to VXL because it will be too much power for me as I'm actually trying to enjoy driving and getting good, rather than just crashing! lol but i am wondering if they make a replacement motor of a different brand that will hold up better than the titan 550? thanks guys!
