I started off boarding the bottom of the spoiler bay with medium 1/8" balsa, then added a 1/4" square spruce "spar" across the front edge. I let the spar in under the veneer, and wedged it in with scrap balsa. There is a gap of white foam - this will be divided into two servo bays. To close things off, I used some of the balsa to cap each end of the bay too.
In this image you can see one of the slight "ripples" in the top surface veneer - this will be dealt with top and bottom, shortly.
Remember I mentioned the flap size? Here is one with a standard sized retract servo placed on top for comparison.
|I even tidied the bench! Yes this is tidy.|
