technical rc i did check everytime with the guy i was sharing with. You cant call me a liar cuz im not lying. You can even ask him. But i agree with you tho. And there was a frequency board by the track but i guess he didnt wanna use it. But otherwise it wasnt bad with frequencies. Most of the time people were checking otherwise brian was making sure people ran that were different frequencies. But if you decided to drive on your own on the side it was at your own risk as far as im concerned.
