No need to plug in to a computer. No firmware or software updates!
As you can see, the gimbal assembly and installation was straightforward, no modification. The landing gear on my craft is a unit also sold by Helidirect (F550FPV-LG)/ I used three oversized nuts and bolts to mount the gimbal to the CF plate on the landing gear. This gimbal will also directly mount to the F550/450.
Compared to other brushless gimbals, I have found this one to work quite well. It also has some cool extra features.
