Congratulations on getting your heli up and running, and I hope you have lots of fun. However, I have to ask this: Are there seriously no laws or regulations against flying RC Aircraft so close to built up areas, and close to people (ie, in the street near houses), in America? The street, what we see of it, is empty in that photo, but at the time it was taken, that emptiness could have changed at any moment, plus people in cars could quickly turn up.
If there indeed aren't any of the sort, which appears to be the case after reading the AMA documents a while ago, there is a serious lack of common sense from a lot of Americans after watching many videos of regular people flying their models. If you lost control of that model, be it because of a technical fault/failure, build error, or merely lack of skills and judgement, think of what would happen if a child, or even an adult just happened to be walking by on the footpath, or even stood watching nearby. If you plowed it into them there could be serious injury, perhaps even death if you think of the worst case scenario.
In a fair amount of the Alan Szabo videos, such as the indoor 3D flight video on YouTube, he's literally a few meters away from the model he's flying while he's doing all sorts of (fast) 3D maneuvers. Despite his experience and skill, he could still twitch or have a failure and lose control, and either injure himself, or plow it into the crowd that isn't a large distance away. I'm pretty sure that someone would intervene in order to stop him if he was doing that here in the UK.
Edit: Sorry for going off-topic in your thread but I'm curious as to the answer. From the videos I've seen, so many people seem to ignore the overall danger to themselves and others, especially when it comes to helis.
