To John's with Isobel, charged battery and dropped of flapperon hardware. Later cleaned and sorted aircraft stuff onto table in corner of garage. Got flapperons down and packed together. Made flapperon hanger rib template from a short rib cut off piece. Drilled aft/outboard (as they call it) center hole after lots of measuring, but did not set angle forward hole. This will simply help me draw circles on wing to align it initially prior to checking for moment.
