Hi, I am about to order an Esky Honey Bee King 2 and I have heard that the stock motor is horrible. If I buy this motor, http://www.xheli.com/ek5-0004.html, and this ESC, http://www.xheli.com/25aescusefor.html, would it work with everythign else stock?

Also I am new to heli's and I was wondering how difficult it is to set up these two parts on the helicopter, ex. taking off previous motor and ESC and putting on the new one?

Thanks!
