I installed the fuel selector plate earlier between the pilot thigh support ribs which are now floxed in place. I then took 2 pieces of 1/4" white foam and made the support floor piece. epoxying the 2 together kept them curved after cure which i think is better than rutan's "put it in the oven" approach. I also added a strip of foam and glass between the supports for added rigidity. After installing the fuel lines and relief tube :) I will glass the floor in place.
