On next January (2015), I'll be visiting the Mukumbari cable car (still under reconstruction works since 2008) located at the city of Merida, Venezuela. Being the longest and highest cable car in the world ( ! ), it runs from 1500 meters above the sea level (in the metropolitan area of Merida CIty) up to 4190 meters in Pico Espejo (close to Bolivar's Peek, higher in Venezuela, 4980 MASL), in a 8 mile, 45 minutes, 4 stages, 5 stations and very impressive trip. I'll take there my V3 P2V+, and some other handheld cameras/gimbals. The plan is to perform some promotional film/photograph landscapes (not seen by public in the last years) and current work status in the different stages/stations, making some aerial and ground (mountain) level videos/photos. Also, as the while site is route for treeking, mountain bike, peek climbing and expeditions, we'll be performing some drone-assisted SAR drills/experiments, in support to local rescue teams. Not having any height flight limits (actually legislation or restrictions about drones don't exist in Venezuela), and being out of the reach of FAA!!! () the only limits are stablished by physics/enviroment/wheater/security staff, owner crazyness, drone integrity and sadly, battery duration. Already got 4 batteries for the journey, and trying to get some more..... Any sponsors? ) Has anyone experience flying at such altitudes? Are known some tech specs stating max (or recommended) flight altitudes? Any suggestions? Comments? Fears? Jokes? As it look too easy... I also plan to experiment in such extreme conditions by lifting up some very small payload in an attempt to help victims or hurt/lost people by droping small cargo over them (may be a walkie talkie / cell phone / gps / or very essential first aid kit. I have been succesfully using a Raspberry Pi (that has input/outputs) onboard to activate / control the dropoff. More details about this to come. Also here sponsors are being required. Any help/info would be highly appreciated.
