I got an Efite Blade CX2 micro helicopter for Christmas this year and naturally I have gone through a few replacement parts so far, so I decided to start making Instructables on fixing the darn thing. I did this as a slide show as it is pretty much self explanatory. All you need for this repair is a new blade, in this case two, make sure you have the correct blade as the blades for the top and bottom rotors are different. You well also need a mini Phillips screwdriver, they give you one with the helicopter in the kit. I am changing the bottom blades in this case but the process is identical for the upper blades.
