400 feet is impressive... I've not had the strength to hover mine above 180 feet yet.There are so many threads on max distance but there is no reason we should have any issues going out 400 ft, its much further than that. The fact I have full RC strength and it momentairly drops off to zero when i am doing nothing and pointed in the same direction and not moving seems to suggest some sort of flaw. Some people have been blaming the latest firmware but that's really all that I run. Is there anything else that can be done to avoid this happening?
Plus the weather is not the best here in the UK right now, it's winter and winds are up and down.
