RE: EP airboat build
When you set up a electric you need to know how many volts your motor runs on . You said it was a 3600mah ( Volts ? ) which will give you a longer run time BUT are quite heavy. Weight in an electric is not your friend . You also need to find out how many amps your motor draws with the prop you intend to run on it . After you find out how many amps you are drawing you need an ESC that will handle that many amps and then some or you will be burning out your ESC(BIG $$$$$ ).
