Important Note:
Make sure the AIO’s slightly bigger size can fit your own quad! The size of this AIO is 36.5(L)*36.5(W)*7.0(H)mm.
We suggest you use this AIO on your 3.5″ to 5″ cinewhoops/long-range or lightweight quads. For quads below 3.5″,
you should carefully check if your quad has enough room for this AIO.
