Sorry, i'm from belgium and writing english not all well. I bought the boscam ts 321 and the rc 802 (on ebay). But after install, the channels are'nt corresponding . When i choose channel 1 on the ts, the channel on the rc is 5! ts channel 8 is on the rc ch4 ts ch7 is on the rc ch 1 . And so on. My question is, is this normal or a defect? My first flight has after a few meters some interference. My screen is a fpv 819A.
