So this can work but isn't necessarily an ideal option for a quadcopter just because of size and extra pins broken out on it making it kinda clunky and most of that isn't needed for quadcopter control. These types of receivers with a output for each channel are usually used on fixed wing planes where you want to use Ch1 for throttle on a motor or an engine and say Ch2 is rudder(yaw/ left right), Ch3 elevator (pitch/up down), Ch4 Ailerons (wing flappies). In that case you want all the separate outputs cause some of them can drive servos that control all the flappy bits and can send throttle to something that makes thrust and knows how to read a "servo pwm signal" that this thing normally outputs. I think
@Dugdog47 maybe had a post about how to switch this receiver to iBus mode or it may be in the user manual but you'd want that where you are sending all the channels through a single line over to the FC and the FC deals with it all from there.
There are many TX options available for mini quads. While many would recommend a high end transmitter, beginners might choose to save a bit of cash on selecting a TX. FlySky transmitters might be some of the cheapest options available on the market, and we will explain these options in this...

^^ lists out a lot of options for transmitters and receivers and explains in more detail than you'll get on any sales page what the actual advantages/disadvantages of any given TX/RX are.
