These are the instructions for the large helicopter. The instructions are similar to the official LEGO instructions and come in pdf format. The partslist of this model can be found on Rebrickable. Please note that the four servomotors and two of the IR receivers are only needed if you want to have motorized flight surface controls. If you are fine with manual flight surface controls you can omit these motors. You still need the four M-motors and the remaining two IR remotes and receivers to control all the other functions.
