Query: Fun....but tuff to controll

I got this toy a day ago, I took it out to fly it and I was having fun until it started going straight and I was using the controller to make it go right and it just kept going straight. Then after it went straight for a while, it just started to go in circles and I couldn't controll it. Then it just crashed. It was fun until i lost controll
