Just a tip for anyone thinking about a Blade 400..
Repace the servos with better quality ones..
here is a video of my faulty servo.. it caused two crashes on the Blade 400 before I figured it out..

or better still just go with a Hobbyking 450 kit and build it yourself.. you'll get a better heli at a fraction of the cost..
