Dji 450 Pet Bottle Leg

Made a quick Flame Wheel Arm landing XTensions to my TBS Discovery Pro and Clone (with Dji 450, 550 arms) because I live 20 meters from the sea.
Always ends up there sooner or later when I fly, now above water
(But they spin so fine and blinks under the water for a while)

On the water I use the appropriate size pet bottles which works great.

Edit: Tried 33cl bottle of Coke on my F450 with large battery (8000mAh) and fully equipped and it worked poorly, be careful and try out in water whi
