I take off ok, it is a little rough wants to yaw but it gets up in the air and seems to be ok. Then it starts to come down so I give it throttle. It seems like it has less and less power and finally just lands. This takes about 15 seconds. I can repeat the above immediately.
I have calibrated the radio, Acels and compass. Also I Calibrated the ESCs. The battery has plenty of charge I tried multiple batteries.
