Query: WORST THING EVER

I FLEW THIS THING TWICE. THE FIRST TIME IT WENT ABOUT A FOOT IN THE AIR AND TURNED UPSIDE DOWN FALLING BACK TO THE GROUND. THE SECOND TIME IT WENT ABOUT TEN FEET UP AND WHEN IT HIT THE GROUND IT WAS BROKEN. I CAN STILL HEAR THE MOTOR WHINING BUT THE PROPELLER WON'T MOVE FAST ENOUGH TO LIFT IT UP. IT WAS FUN FOR THE 30 SECONDS I USED IT, BUT OVERALL-WORST SPENT 20 BUCKS EVER!!!!!!!!!!!!!! DO NOT BUY THIS, IT IS JUNK
