Kenskid, You will have to totally strip you heli to change the main frame. Servos, 4 in 1, main bearings, LG, and Tail Rotor. You will need the thin black mounting tape and the little zip ties that come with it when putting it back together. This is what helis are all about. Strip it,[sm=confused_smile.gif] fix it,[sm=idea.gif] admire it,[sm=shades_smile.gif] crash it[sm=cry_smile.gif] and then start over again.[sm=thumbs_up.gif] LOL Also once you change the main frame one time you will know your heli inside and out. Good Luck Gittle
