E-sky LAMA V3 Co-Axial 4CH Electric RC Helicopter (RTF)
Very easy to fly at indoor. When it goes in air and become stable, you can even release the contorl sticks but it still remains in there! It is the easiest heli that I tried.
The bad thing is the rear tail is easy to break in just a little crash, Lets get some tail frame in to basket.
