I have been a long time RC enthusiast, but ive never gone to a track and raced. Therefore I have never had an issue with mixed signals. I have a SC10 Brushless on preorder that comes with the XP3-SS 2.4GHz 3-channel radio system. So my question is when going to the track how do I know what everyone else is running so signals dont get mixed? Wht if all my possible signals are taken? or is that not possible?
