Iron Dog

As this is the first panel of the laser-cut wings to be built, I feel the need to test the fit of the wing to the wing saddle.

Perfect fit -- you did great, Steve! Thanks!

Bottom sheeting completed. I sliced along the laser-cut perforations at the trailing edge of the ribs to cut the split flap free. Flap and aileron hatches installed.

Second panel underway. I found it much easier to cut out the half-rib portions of the split flap before sheeting both sides, this time. I cut them loose, then tack-glued them with just enough medium CA to hold them in place while sheeting.

Finishing the basic structure of the split flap:

Dihedral brace installed and wing panels test-fit together. Fuse set on top to double-check fit to wing saddle prior to the first prototype wing joined. Again, I am very happy with the fit.

Visible in the background of the first two pictures is the original design of my wing. The original design was hand-cut using formica templates; and the wingspan was extended 4" beyond true scale. This new CAD-designed wing is true to scale. Yes, you heard right, TommyGun . . . aside from a 1" extension in the tail moment (to compensate for the weight an engine mounted in the nose, rather than mid-fuselage mounting in the full scale plane), this new wing design means this plane is exact 1/8th scale!

Found it necessary to reinforce the structural rigidity of the flap with 1/32" ply glued to the inside.

Second wing started:

During the build of this wing, I detailed better shots of the modifications to the wing for installing fixed gear block, rather than retracts the wing was designed for. I used the cut-out for the rear retract mounting block, and extended it forward to compensate for the additional width of the single fixed gear block:

(Pic 1) Block put in place against rear retract rail cut-out;
(Pic 2) Razor saw used for depth-cutting the additional width from the ribs, at angle;
(Pic 3) Cut-off wheel used to extend the width to the depth cut
(Pic 4) Final picture shows me sanding the necessary angle in the ribs at the original rear cut out.

Four wing panels largely built now. Marking where to drill holes for Robert Hinge-point hinges for split flaps.

Success -- they work! Not bad for my first time designing and building split flaps.

Iron Dog

Wing halves joined.

Wing tip blocks glued on, and carved/sanded to shape.
