you guys keep talking about this channel or that channel... are you matching frequencies with the IRC? channels are frequencies, so whatever frequency/channel you set on the transmitter, simply find that channel on the receiver and tune to it. don't search.
The reason I have suggested that is because I have found in my case that the channel I am on with my transmitter and the exact channel freq. on the receiver is horrible and the distance is short. My transmitter is 5860mhz or channel 7 and the channel that I receive the best and has the longest distance is A1 and is 5865mhz. or channel1 on the LCD I fully understand the frequency match, however in my case it doesn't work as good, any idea why? I have tried both only to find A1 works better.
