First I don't care if this has been asked before or if it seems stupid to you. Go to another post. This is why this is here to ask questions and to answer them so please don't be douche bags. Thanks. "To avoid signal interference do not use other 2.4 ghz when flying" I'm not fully understanding what the statement is. Or what a 2.4 ghz is. Lol. So please help me understand more. The reason I ask is I was on the beach today with no wind "hardly", and only made it like 800ft out and lost compete connection for about 30 seconds. So I'm trying to figure out why. Yes the bird is safe. I was in line of sight so was able to control it even though I couldn't see. Yes the antennas were positioned correctly. Thanks in advance.
