So I've had this truck for a while now but there has always been something wrong with it that would make it so I couldn't use it but now I have everything running properly except for the receiver. What is happening is that when I turn on the remote then the receiver it will connect for about 30 seconds max then it will disconnect, and I have tried just about everything to fix this problem like brand new batteries brand new receiver and it still won't stay connected and I have no clue what to do from here any help would be very much appreciated!
