I love this part on every bit of the project, it's assembly time. I back riveted the stiffeners onto the skin and basically followed the assembly guide and riveted the aileron together, as I expected, it turned out lovely. The only tricky part was riveting the top rivets which joined the two skins together with the spar. Just a point of holding the aileron in the right spot and and contorting the hand to get in the tough spots, hey presto, it's done.
