Hi everyone. Today i was driving my T-Maxx 3.3 and everything was just perfect and then I decided to connect an iphone to my transmitter but when I took it out and kept driving I started losing connection with a truck. It just goes like 8 meters away and thats it, I can`t turn or throttle. I thought the batteries died and put the new ones but it didn`t help. What could be the problem?
