2 Chanell rc plane

Can anybody tell me how and wot i need to convert my 2ch rc plane into a 3 ch.

u need a new reciever and transmitter (Remote) which supports 3 channels. but its better to buy a 2.4ghz 4 or 6 channel transmitter and receiver. fix the reciever on ur plane and connect the wires to it and u can fly it. to make it 3channel u need servo and pushrods or u can make the pushrods with steel wires (14 or 16 guage). well i'm just 13 year old kid so i'm just learning these stuffs.
hope u get what u want. oh and if u need details email me at <email>

3rd servo. but you need a 3ch rec/and trans what make of radio you got. ?

well a 2ch plane is your basic throttle and rudder, so if you want to convert, just add more servos, creating an elevator, ailerons etc. but there is more to converting, we have to know what plane your trying to convert, or if its even worth converting...
