I'm from Germany and u have to excuse my mistakes. I play on a non-hive server and after a while it got really boring ... so I had the idea to implement the RMOD to this server. We wanted the Little Bird, the BlackHawk etc, but then we recognized, that it's not possible to play with them.... because they have this fucking radar which shows all vehicles and players in a radius from 800m. And as I heard the UH1H had the radar too and it was removed by Rocket and his team... so it's kind of possible to remove it. So my question is, how can i remove it?
