RC control for helicopters vs airplanes?

Can you use the same RC control/transmitter for both helicopters and airplanes or is the RC control.transmitter for the each different? I am considering buying a 6 channel transmitter and a helicopter and was wondering if in future i can use the same transmitter/RC control on an airplane should I buy one later on? Any input would be appreciated. Thanks.
