We have been using them for the past 2 seasons in 2 cars. Only had one problem with a Twister model. It was our fault as the leads can unsoldered and applied reverse voltage to it after a BIG hit. KO replaced it for a small fee. I suggest that you change the profile to one on the KO web site. It really makes a differance. We run the caps and diodes on them as suggested. One advantage if you also run the KO RX is the lower BEC voltage setting. The 302 RX will increase the voltage so that it operates correctly.
