These people need to get into a LOT of trouble. This is not legal, and for good reason. I say this from the perspective of having designed, built and flown RC fixed-wing and helicopters for well over twenty years. As neat and sophisticated as they might look, these things are still toys.

They are not built to the same standards as real aircraft. Single failure modes abound and they are, in most cases, catastrophic.

I have seen model airplanes loose a horizontal stabilizer in flight for no apparent good reason. Or simply fall out of the sky like a brick when one of the cheap electronic parts inside fails. Figure out the kinetic energy of a 8 to 10 pound object travelling at 100+ miles per hour to understand the lethality potential.

The airspace he covered is flown by full-scale aircraft. Imagine being a tourist taking one of those NYC helicopter flights (done that) only to plummet to your death because some a-hole decided it was OK to take his $300 toy on a joy flight.

Beyond, that, imagine if this was, in fact, legal. Would you like to see 100 of these things flying without control around an airspace such as NYC? Bad idea.

They need to get into a LOT of trouble. This is definitely not something anyone should emulate or replicate. It will ruin the model aircraft hobby in the US forever.
