The right-hand doors no longer fit and will need a lot of work to get them to work correctly. Looks like the large door has warped. It will be interesting to fix them.

This is the hinge setup for the fowler motion. This will be tested once temporally installed. This will be interesting to get the correct motion to match the outer flaps to the inner ones.

Better shot of servo brass tubes setup. Need to get lighting system ordered and installed and flap servo installed before I can finish closing the wing.

Aileron in position and have decided to use the sliding square brass tube as I originally designed as it is way too much rework to use the plastic push rod method.

Massive balsa block created and glued on. This is a B model 25 so no gun position here.

Control attach points were designed for fowler method and flap basically rebuilt. Still will need work on area were the flap meets the center section.

Outboard flaps were in really bad shape. Also had to design the fowler method to match the inboard flaps.

Same setup on the other inboard flap. After way too many years setting stored most of all the ribs were damaged or missing. As mentioned before, this is a semi fowler setup so tomorrow I will add the blockage for the brass tube extension for the hinge.

Center section (inboard) flap rebuilt, and servo linage control attach point created. Linkage is in temp location until I find where the servo will mount best in the center section.

Attached the aileron but will convert my brass linkage to use the plastic push rod method. Reasoning is that brass sliding in brass may create an interference with the radio.

Started work on the central section. trying to figure correct shape for ridge over the wing for each nacelle.

Right side is better. Redid the banding on the turret and now just need to trim it to correct shape

Left side is the worst for not following the curvature of the fuselage. Not too bad, but not what it should be.

If I had to do it again, I would cut smaller strips to go around the tight curves. More seams but better compound curves. I'm guessing 3/8" to 1/2" wide strips with beveled edges.

Push rods in hatch area where they can be pulled out or pushed in. Will install wire inserts that will hold push rod in closed position.

Turret hold down concept changed as screws were hard to locate and impossible to screw back in due to their location. Now using push rod idea. Shows outer push rod with pin retracted allowing servo and turret to be removed.

Cut on the center joining line of the two damaged wing sections using the band saw. Lucky, he had two undamaged opposite sections.

Removed skin around spar to allow for new spars to be clamped in place. Actually, increased depth to the fourth rib after photo.
