Got my first plane!
having a scale spitfire I can say this is not a beginners plane. they are fast, touchy, and difficult to get orientation (that oval wing throws you off) but they are fun to fly and look great in the air.
I would find a trainer aircraft and get an instructor to get you started. then move to a sport plane. I wouldnt really touch that till your 3rd or 4th plane, you can assemble it and get it ready as "motivation" though.
I too came to flight sims on the PC and RC cars so I picked up flying pretty quick. if you practice alot and learn quick you can be flying that thing within a year or less.
I dont know about brazilian frequency laws so I cant help you there. but im sure someone can help you out and get you started.
good luck.
