Under highway flying?

[surplussunshine]

A newly constructed dual level highway is being constructed in a town near me. The bottom level is currently under construction only for a few more months.

Since the majority of it is vacant, how would the p3 handle with all the metal around?

If you loose signal at any point I think she will RTH right into the upper level. CRUNCH !

I'd be flying roughly 1000 ft out or so. This would be video for a later video.

If you're worried about the compass fly it in ATTI mode. I'd be surprised if the compass were affected at 1000 feet

The metal is usually only an issue for getting a compass calibrated and/or initialization on take-off. You should be fine to fly around steel. I think the thing you need to keep an eye on is if you lose GPS signal and switch to atti mode. But you should be fine otherwise. I recently flew all around a metal warehouse and the only issue I had was losing satellite signal when under the roof.

Be ready to hit forward on the right stick and throttle up soon after to get it out of the way. It might be smart to set a low (very low) return to home height so it doesn't rise up into the top bridge if you lose signal.

As someone else mentioned, RTH is your biggest concern. I'd switch fail safe mode from rth to land so that it doesn't try to fly up to your safe altitude in case of a loss of signal.
