RE: first Heli
Just out of curiousity...do you plan to possibly learn 3D flying someday? Or do you just want a fun heli to mess around with indoors?
In my opinion....Iwould skip getting a coaxial heli and get a Blade mSR....although the mSR is for indoors....I don't think you will get bored with it and it is better to learn all the different orientations on than a coaxial and its VERY durable.....you will crash while learning and this little heli gets through crashes without any problems more often than not. (crashed mine many times and never broke anything)
Its also very beginner friendly. People at my job have hovered this heli there first try that have never seen a rc helicopter before. Just one noobs opinion.
