amplifier for 2.4 GHz RC module

Hi
We have a 2,4 GHz ASSAN module, http://www.rcbuyonline.com/Files/252...8F_Combo_L.jpg and we like to build amplifier for this module, to controle 8 servosmotors between two ships in the lac.

So, what kind of amplifier we must use ? class A amlifier ? class c ? other ?
anybody has an electric diagramm to do this ?
