The industry has been using them for ages hoisting Red Epics and D Mk 3's skyward for a long time now.
As far as the film industry is concerned $10,000 on a rig is disposable. They can also use several of them and have them all rolling simultaneously if necessary. As we all know, multicopters can fly places a full size helicopter simply can't reach.
The fact that the FAA was going to 'legalize' them for film use was a given.
Oh... lets not forget how the studios will jump on the argument "Oh, think how much greener it will be for the planet by not having gas guzzling copters flying around...blah, blah, blah"
And of course, finally and by no means least - the palms that will be greased in the process ! :roll:
Oh yes.... the film industry is worth billions and that generates a lot of taxes..... FAA approval will happen very quickly and even if it doesn't or it takes longer than anticipated production houses will just continue to use them anyway!
