I have flown my TH out to 3500 feet and had no latency problems whatsoever. However yesterday I went over about oh I thousand feet to the right and for some reason there was considerable amount of latency between my inputs and the time that the TH recognized the signal. I don't know if it's because I've started flying racing drones and the latency is so quick but this is not a good thing for some of us. I think sometimes the latency is the problem with the TH flying away.
