Sure. I went through SEVERAL Xcelerin systems in my 8ight E. I used all Losi equipment, so they had no excuse or explanation as to why they would just... "Quit". Several ESCs, motors, several incarnations of the software, a new rotor in one of the motors... nothing worked. It would run on average about 20-30 minutes, then stop. I sent them back in each time, and eventually got tired of watching my 8ight E catch dust... so I sold the last Xcelerin I got back from Horizon, and bought a Tekin... been happy ever since.
