whether I press the RTH button on the console or touch the return home icon on the screen, my Mavec Mini doesn't return home -- or go up to the height I have told it to return home at.  It just comes down and lands where it is.  Is it defective in some way?  Is this a software issue?   

Try to flash away from home point more than 21 meters

is the GPS locked on? do you see an "H" on the map at your home point? are you setting home point on takeoff or is your home set to follow your controller?

you have to be at more of 20 meters from the drone to activate rth, otherwise it lands where he is
