The air conditioning system will be your biggest hazard. I was at a large hobby show where the blimp somebody had for demos was stuck up against the induction grille for most of the day.

The story was that while the pilot had avoided the induction grille, he got pushed there when he got too close to a vent and the blimp moved in an unexpected direction.

They had to shut down the air conditioning to get it free. Check with the venue before flight and avoid anything that looks like it might be for moving air.

Of course that was a decade or so ago, so the more modern versions might be less susceptable to this sort of thing.

Since you would be using a transmitter in the arena, I'd double check with FIRST as well. Try using the FRC group.

If they let you and you're bringing it to San Jose or LA can I try flying it?
