you really need to get some lessons before you fly again
Watched the video and have to agree with jetmech. Scary stuff.
The sim will work for beginners, but some of the stuff on your video was simply dangerous.
Sit down at your local club and observe before you get back in the air.
And was that an actual flying field for RC aircraft or simply a parking lot? Maybe find a more suitable site (ie without buildings, cars, curbs, children, etc.).
