I'm working on the aileron pressure boxes for the IV-P. Looking at the available photos, including those from Lancair, some seem to show reinforcement in the area around the pressure boxes. Some don't. Tech support had no answer one way or the other. My kit is a recent fast-build so the door area reinforcement mentioned in the manual shouldn't apply.

Before I bond the boxes in place, have other builders added any reinforcement and if so how much and where?

Thanks very much-  Bill Wade
