There are many options. Depends on who tells you.
You said model, so I am assuming you are willing to build either scale or sport?
Probably the best flying one is the Javelin sport model. Never tried it, just heard talk. For scale the easiest builders/fliers are going to be the 600 series. They are all set up for beginners. Next up would be 900 series, especially if you want a warbird. And when you want bigger and better things, try the laser cut 400 series! Just my opinion, others will definently vary. Have fun!
