Hey Everyone I am new to the forums and to the DJI Phantoms. I am looking at purchasing a P3P or a P3A in January at some point. I read that these units have a 500 meter altitude limit which is fine with me, is this still the case or have they lowered that limit yet to have the max be 400 feet? Has anyone heard of this limit being lowered to 400feet? Is there still currently any work arounds to go above the 500 meter limit for when I go by mountain ranges to get some nice footage or have all of those work arounds been removed by current updates to their software and firmware? Is there an ideal firmware/software version that these units should be left at to avoid any restrictions on these units? Is there any where to find a list of all the firmware/software updates and what they do? Can these units be operated in cold temperatures? Is there any place in Canada to get these serviced if something breaks? Look forward to hear all the responses. Thanks!
