Think reciever or antenna is messed up
I have a sandstorm, and when I drive it about 200meters away I loose signal. I have changed batteries on my transmitter, I have binded a second transmitter and it does the same thing. I opened it up and it looks clean and the antenna is still soldered on well. I crimped the cable a little when zipping up the other cables. It looks fine though. I know I have had it farther then that with no issues. I think I have to assume that the Reciever needs to be replaced now.
