Continuing from last entry. Returned to inboard flaperons and added splice plates. Made sure the rivets were left open for attaching the mass balance weights, but did not fit and drill at this time. It will be easier to deal with that at final assembly when doing the balance. Flaperons are done and turned out well I think. Now back to the wings..
Note from future self: Should not have added the inboard splice plates now. The inboard flaperon sits at a lower angle than the outboard and needs to be positioned and trimmed when the flaperons are mounted on the wing.
