It really depends on what you are trying to do with it. Some things are easier, others not so much but you get better at them as you use them again and again. It can also be frusting when something that looks like it should work doesn't, and you have to look it over ans figure out what you did wrong.
It;s not all or nothing though. I suggest that you try out one or two features at first to see how it all works and then add more things as you get more conformable with it. It really helps if you got something you are trying to do and work to figure how to do it rather than just do random stuff.

Dang don't use PC Mobile here 😅 @HuskyDynamics01

@Numbers2 Use either this or this (I personally use the first one). Both require a PC.

Fixed @ollielebananiaCFSP @Nerfaddict

@Numbers2 you are asking a bit much

It's not exactly hard as long as you start simple: Inputs like what @Griffon1 said is a good place to start

@Numbers2 say please, please

Heyy can you tell me how to code in a Picture into a labe please? @HuskyDynamics01

Well its mostly a lot of common sense, like how "Pitch+Roll" will quite expectedly add pitch and roll inputs, so you'll get the hang of it.

I went from noob to average after learning some python. Its one of the easier programming languages

the programming language is basicly Python <== link to wikipedia

Learn how to code with python and you wil know how to do the fancy SP stuff too @BlackGearCompany

For the most part (until you get into stuff like PIDs and however people do fancy stuff with labels), it's pretty easy. The official funky guide is a very good resource to learn the basics of FT (and even more complex stuff), so I'd recommend you start there.

That depends on you and what you intend to do with it.
Simple clamp functions or stability inputs? Not really.
PID algorithms? Most likely.

Yes

@BlackGearCompany For most things yes.

@temporaryplanetester knowing only simple algebra is enough to learn the FT?

It's kinda like a programming language, you might have an easier time learning it if you learn the basics of JavaScript or Python first.
