I will second (third) everyone's recommendations here... and will add, Don't be like me!
My RC journey started with a 2m P-51 foam BNF I bought 3 years ago...
(Figured that should NOT be my "Trainer" so) I found Flite Test and (like you) really liked the look of the Dr.1 and Se.5.
I bought both and here's how the maidens went;
You'll note BOTH videos are under a minute... It was a LOT of work for under two minutes of flight!
I didn't give up though (both planes shed their wings that day...)
and just recently revisited the Dr.1 (with the help of some friends!) after both my skill flying and building has improved a LOT!
Now I run out of batteries before I run out of props or planes, and that is a great feeling!
So my advise, heed everyone's suggestion and start out with the "boring" planes first (Tiny Trainer are the Scout are my favorites.)
Then come back to the cool stuff! (I'm still busting up Mustangs!)
Oh, and Welcome!!
