Seems like I missed something. Well i came back and click the page and saw so many wonderful advices. I should have came to check earlier. Thanks for all your advice, they are useful.
Have read every post and think that joining a club and finding a instructor are the first i would do. Also, i should think about every detail before i buy a plane. But just wondering, most shops title their RTF plane as scale mode for "beginner", but as you said never think about scale when i start...what a real beginner's plane features?
