RE: Question about position of switches?
There are 2 switch holes in front because we use the same part for the fuse side on both left and right. It was not meant as a radio switch mount.
There are two mounts in the rear also. But I prefer to mount my switches above the wing so that the rear screw mounts into the block that supports the hatch hold down.
I've attached a photo. Do not cut into the longeron at the top of the side that runs front to back.
