Hi
Yeah as @Stallen (also congrats on your ranking!) I would suggest starting with a simulator is a great place to learn to fly as you dont exactly wanna learn on a £200 quad and crash!
The other option is to just buy a cheap toy quadcopter like the CX-10, as if you can fly one of these then you can fly anything.
Once you are happy to fly and want to give a go at building your own, our current DIY beginner kit is the QAV210 quadcopter, which we have the first part of the assembly guide here
Lastly as you said you prefer something small/indoors then the CX-10 is great to learn to fly, but then if you want something for FPV flying I can suggest you get yourself a QX90 (or one of our other brushed indoor FPV quadcopters) along with a flysky i6 radio and some FPV goggles.
If you have any other questions just let me know
