This needs to be 'EMPHASIZED" strongly, especially to newb's who are recommended to start out on the H in "Smart Mode" to get assimilated . Make sure before you take off or land in Smart Mode, that you step back and "ARE" at least 26 feet away from the craft. If not it WILL try to reach the 26' point and in doing so crash into any object in it's path !. Also while landing, the SAME THING ! Land it 26' from you and the controller, or it may not land and idle motors as it is trying to maintain 26 ' from your position ! And tip over or fly off ! I call this the " The 26 foot Smart Mode circle of DEATH" ! And it is not funny ! It has happened numerous time! And why Yuneec has even installed this is ludicrous, as it is more dangerous to you and you aircraft !
