Personally, I'd stay away from the cheap gimbals. See if you can save for one of the popular ones, ie, Rotorpixel, Ariel Freaks or Taco. They will cost more but they will be worth it.
Im sure there's a thread on here that compares all the gimbals, ie cost, weight etc
Hi friends... one question about gimbals...
I see these chinese gimbals works with 7.4 or 11.1 batteries, and 150mah comsumption.
is it good idea install an external battery to power it? (and avoid any problem to main battery)
I found 2S 350mah with 27grs. It´s supposed to be enough to power (I don´t know real time)
