I was just wondering what the FAA will do when (and I believe it's coming) lighter than air RC airships become popular that have 4k cameras, can hover in place, have ranges of more than a mile, can travel at speeds close to 30mph etc. As it stands now, "Lighter Than Air" RC video platforms would not need to be registered since they are "lighter than air" in the flight configuration. Would the FAA be sneaky and insist that the weight (before Helium is installed) must be the weight? What if the entire craft is still less than 250 grams with no Helium? Would overall size become the deciding factor? Since the "guidelines" are in place, would they quickly re adjust the rules? If safety is the concern, why should they? Hasn't everything that needs to be covered regarding sUAV's been written for the most part? Seems that if they re-adjusted the laws to cover lighter than air RC aerial cameras it would be proof positive that safety was never the issue. I guess I'm just skeptical of the intent of the Registration and all the laws governing hobby aircraft. Congress limited the Governments power, yet, here we are. Apparently, Congress has become beholden to the Executive branch. This was never intended. What say you?
