I saw another vid where a guy lifted a water bottle with around 2kg of weight to it..
it barely makes it, but it did lift.. but can hear the strain on the mavic prop trying to achieve flight..
not sure I wanna put my bird through this kind of stress..
well, I went home to weigh the firecrackers, with the box it is rough 1.3kg... could be slightly lighter without the box..
shrugs..
I was playing around with a lighting rig for my Mavic pro, to maybe use for search n rescue with my fire dept. or night lighting for photo shoots. I decided to get those LED lights that some intermediate photographers use for set lighting. Many of them are very light, and put off an extremely bright light. I went with 1-5x7 228bulb LED light, and 2-4x4 96bulb LED lights. The mounting brackets attached to the Mavic weighed out at 120g / 0.26lb. The 5x7 light, with battery (which weighs almost as much as the light) weighed in just shy of a pound at 435g / 0.96lb. The two 4x4 lights,together, with batteries only weighed in at 220g / 0.46lb. That's a total of 775g / 1.7lbs. With all three lights attached It lifted off quite easily, it flew ok and hovered just fine, (I didn't fly it hard, but I didn't just let it hover either) but right at a minute, each time tested, I got an "ESC/motors high temp warning, So I landed it immediately.. It did the same thing with aftermarket, light weight props, carbon fiber props, and the Flash-Word LED props.(All props were the newer low noise design).
I removed the two side 4x4 lights, which combined (5.5w. 800 lumen each) put out less light than the 5x7 light, (20w,2000 lumen) so it's still lights up a decent size area at an altitude of about 20-30ft. / 7-9m. With the aftermarket lightweight props, and just the one light, there was a really bad, shaky wobble. I tried re-securing the light to the mount, making sure everything was tightened down and snug, still got the bad wobble. With the Flash-Word LED props, the wobble was less, almost tolerable, but it drifted a little when trying to hover. With the carbon fiber props, there was almost no wobble at all, only after a sudden stop or turn, it would wobble slightly for a couple seconds, then hover normally. I flew the carbon fiber test around 5-6min, flying a little agressive a few times, and never got any ESC/motors heat warning. With the light weight props only, the wobbling caused an "unstable gimbal" error.
I'm working on a bigger light set up using the DJI 550, and a water cooled LED light that is 1000w, 35,000 lumen, I'll post results on a misc. thread when I get done with that project.
