Tell us what kind of radio you have with the helicopter. If it is any of the top brands, (Futaba, JR, Hitec, Airtronics, Multiplex) sobody here should be able to tell you how to do it.

For this type of helicopters, the term Ready-to-fly refers to the airframe being assembled, not the servo connections being made. This is not the cheap type of helicopters that come with their own radio.
