I haven't heard anything positive lately, just a lot of hear say. If the FAA moves like most government entities it'll be a while before anything happens. As far as "grounding" goes, well that all depends on who you ask. Ive asked locally and nobody here has told me no, so I'm not too worried about it. I guess I'm in the fortunate position though to have had a backup plan in place for just such an event. Truth is I use the mast a lot more than I ever used the helis or planes and it's a whole lot easier and safer to use in urban environments than any of those ever were... just have to watch out for overhead power lines is all, and occasionally I have to use guy ropes to steady it when the wind pics up. Other then that I prefer it any more to any of the airborne systems.
