OK so today I whent out to fly and take off is perfect hovers pretty straight doing a little to and froe as I decided to taker up little higher and put some real motion it takes off like a bat out hell then does a flip after I let the stick go u can hear the motors going all out to straight the quad up but just never recovers same results every time I've checked my balance and it still nice and level all props are tight motors are good as far as I know no funny sounds or tight feelings or hitching felling
