Re-understanding Flight Control& Motor

The traversing machine is mainly composed of the following parts:Flight control-this is the brain of the crossing machine, which is responsible for controlling the flight of the crossing machine.

Remote control & receiver-this is the ear of the traversing machine, which is responsible for receiving the instructions of the flying hand.Picture transmission & camera-this is the eye of the crossing machine, which is responsible for sending the captured image back to the glasses/screen of the flying hand.Motor & Electric Tuning & Blade-Power System of Crossing Machine.Battery-the energy source of the traversing machine.Frame-the "body" of the traversing machine, bearing all the parts.At present, flight control, electrical control and image transmission usually appear in the form of flying towers, and sometimes they are integrated into one board. 

There are many kinds of flight control called aio(all in one) crossing aircraft, such as mwc flight control and kk flight control when crossing aircraft first became popular, cc3d and f3 flight control that were common in previous years but are out of date now, and f4/f7 and top h7 flight control that are common today.If some students who have played with self-organized aerial cameras are reading this article, they may wonder: Why didn't you use pixhawk flight control, apm flight control or cheap qq flight control, which are common on aerial drones? 

The answer lies in the fact that the crossing machine mainly operates in pure manual mode, which mainly tests the speed of flight control from receiving the remote control signal to analyzing the remote control signal into motor control, as well as pid adjustment, filtering and other tasks. The calculation ability of flight control such as apm is relatively weak, and its weight and size are not suitable for crossing aircraft. We usually use f4 or f7 flight control with bf or inav firmware, but firmware such as emu, rf and falconx is also worth trying.So what is firmware? Firmware is the operating system equivalent to flight control. Different firmware has different characteristics and functions. 

Just like linux and windows, unix and dos.F7 or f4 flight control is still recommended. In any case, f4 is the configuration that needs to be achieved at least. First of all, from f4, the flight control performance has made a qualitative leap, which is enough to hang f3 and below, and it has stronger ability to calculate, process and control the attitude. Secondly, the new version of betaflight no longer supports f3, and f4, f7, h7, etc. are the flight controllers that are attached to the version (laughs).Flight control will generally be sold in the form of flying tower or aio. Remember to buy one that is compatible with the mounting aperture of the rack when purchasing (it will be explained in detail in the installation section). Flying towers usually combine flight control, image transmission and electrical adjustment. These components are integrated on several stacked circuit boards (as shown below), while aio is concentrated on one.
