I mounted the inboard servo using the long screwdriver that Andreas recommended to get the "bite" on the 2.9mm screws. It worked. The screws were quickly installed.
I added the extension for the outboard servo and put heat shrink tubing on the connection. The previously created connection for the inboard servo is hanging on the right side.
I dropped in a bare wire from the root rib and taped it to the two servo extensions (also with no connector yet).
I pulled the extension up through the inboard aileron servo rib that has the hole for the extensions to come through. Both servo extensions have about 18" of wire left and no connector until I figure out what and where those wires are going to connect.
