About The SpeedyBee F745 35A BLS 25.5×25.5 AIO Flight Controller
This is an AIO (All In One) Flight Controller. This means you get everything you need to fly your drone on one board. You get the functionality of a Flight Controller and the Power Distribution of an Electronic Speed Controller. This board comes with an F7 chip, so it can take a beating in terms of peripherals that you attach to the board. It does have Bluetooth which means you can use the SpeedyBee app to configure your drone wirelessly and without a full size computer/laptop. You get a digital VTX connection onboard to make using digital systems like DJI and Walksnail Plug and Play. The ESC part of this AIO board supports up to 35A for batteries ranging from 3S to 6S.
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.

The SpeedyBee F745 35A BL_HELI_S AIO (All In One) Flight Controller comes in a 25.5 X 25.5mm size. The overall size is a bit bigger than your typical 25 x 25 AIO FC (Flight Controller), but it comes with tons of features which make the size totally worth it.
