          The balance on the elevators... On the plans show the scale balance, sport scale balance and no balance for tow plane duty. You can kinda see them (the diagonals) on the lite ply center piece.

                    • Well Dean, here is the next segment. Wing Structure begins.
                      Pretty much self explanatory.

                      • So the outer wing panel is a continuous build off the inboard wing panel. The outboard bottom spar sits on a "jack stand" and the ribs have build tabs that progressively get longer as they approach out towards the tip. The wing break joint assembly has a CNC 1/4" birch ply joiner that gets epoxied to the bottom spars. The joiner and ribs are half notched so they key into one another.

                        • Add another rib and then the servo wire conduit tubes are slipped into place. Then the remaining ribs are all glued in place.
