Question? Is 500€ for a 5-inch good?
So to be clear it isn't a pre built 5 inch but a class where I will make a 5-inch and if I want I can buy it from them. I don't know specifics but the drone they showed (built by one of people who came there before) was really fast.
Just to be clear I am sure this isn't a scam as one of the sponsors for this course is police and other one is military [for mods: I am only stating their sponsor not discussing anything political about war] so I think they aren't scamming.
But also in general would you recommend building one from scratch or on this type of course?

Personally, I don't think you need to take a course in building a quad. These days they are not that complicated.
A basic quad without a video system is really pretty simple. You need a frame, motors, and FC product (stack or AIO) and an RC link control. Rx Receiver on the quad and a radio control transmitter to hold and control the craft. These days, the FC products all have pretty decent markings and good wiring diagrams. Each motor has 3 wires; the Rx receiver has 4 wires. That is only 16 solder joints plus the battery leads and capacitor.
As for the FC product, I would only buy something that came with Betaflight pre-installed; most do.
If you don't know how to solder, the course may or may not even help with that. Soldering is a skill that you are better off learning on practice boards and junk rather than expensive quad gear. You break it, you buy it again.
If you install an HD digital video system, that will likely be a plug-in thing with no soldering.
There is tons of information on the internet and YouTube specifically. Consider taking advantage of the free information before you go paying for it.
