Approximetly how much is the drag coefficient if orginally the coefficient is 0.02689. I know it depends on aircraft etc but I am only looking a rough estimate.

As a first order guess, spoilers are a flat plate. But, what outside sources have you consulted?

Books, AIAA journal papers, NASA technical server, etc. What exactly are you trying to model here?

i am modelling the braking system. so i need to know how much drag the spoilers provide to enhance my model

Have you tried Raymers book?
