centre of gravity of an aircraft with three lifting surfaces

[StephenC]

Hi

Can anyone suggest reliable methods or tips on locating the position of the centre of gravity of an aircraft which uses a canard configuration?

Thanks

Not sure if this answer is too basic, but I guess the standard stability equations will do?

I think it highly depends on the amount of lift provided by each surface. I think the above answer should be a good place to start (Stability Equations).
