I finished assembling the tailcone for my 12iS yesterday. Today, I noticed the lower side skins on both sides are slightly depressed, just aft of the forward frame. I can push the skins back out from the inside with my hand, but they immediately pop back in (like an oil can!). Has anyone else noticed this? Does it resolve when the tailcone is attached to the main fuselage? (You can’t really see it in the picture; the arrow points to where it’s located).
