One other hinge ready to go. I think I will tack weld the G10 in place with Aeropoxy making sure of the alignment, let it sit overnight and then install the blocking with more Aeropoxy. Bad thing is that the hinge structure will not be able to be removed without destroying much more material by using Aeropoxy. Did I mention, it's got to be correct this time.

Better shot of dry fit new linkage attach point with 1/2" mounting material and my made-up square to make it plumb. Large area of skin replaced getting stuff removed this time.

Flap with all hinge items removed including the servo linkage attach point, it was not installed perpendicular or plumb to the flap. Some skin replaced

Left side removed but damaged the skin getting it all out. Will patch the skin after install is complete.

Right side with hinges and support material removed. This is a real pain to do.

First glue up of hinge on right side flap. Ensuring that the hinge is perpendicular to the flap.

Same setup on the left side flap. Once Tightbond has dried, I will reglue with Aeropoxy on the edges. Sure, was a lot of work getting here.

Hinge assembled. Holes drilled for glue and surface scraped for better adhesion. Pivot bolt tightened down to stop rotation and then back off about one half turn to allow easy movement.

Dry fit without the attachment items in the flap. Will drill for pivot location and install bolt and nylock nut. Had to open skin on the flap to have access to glue in attachment sections. Going flying tomorrow and will pick this up after I get back.

Different parts for the attachments in the wing. I have included a 1/64" shim to open up the 1/8" area so that there is less drag on the hinge when it rotates.

Mounting blocks not installed but shows basic design. Undecided on G10 section in flap as to how to mount for best strength.

Just cut one hinge setup but looks pretty good. Could only spend the morning working on the project so will pick this up tomorrow.

Temporary gauge to set correct height. Tomorrow will use Aeropoxy on hinge section in the flap after shaping flap to miss the fuselage and inner section.

Changed from a drilled 3/4" block to the same sandwich technique used in the flap. This also allowed for a larger, stronger bond to the rib and wing.

Left flap. Elected to not glue Robart hinge in the brass tubes and just use the set screw. This allows for removal and adjustment if necessary.

Right flap. Each hinge location was slightly different and the sandwich of 2 spacers, the slotted hinge arm holder and then the end cap allowed a stronger and more manageable arrangement.

This sandwiched approach allowed for more ability to set the correct angle and location. Temporary spacers in place to set location of flap.

Hinge rotation point drawn out on plans and dimensions held from hinge to hinge. Location and height are critical to get the flap to work correctly.

Brass tube to be glued in plywood keeper. There is a spacer, the keeper, and then an end cap to hold it together.

Here is the hinge setup. I will need to drill and pin to make sure the Robart hinge does on pull out of the brass tube. I will glue the hinge in the tube but want to make sure it does not pull loose on flap deployment. Block in standard 3/4 " pine, drilled and shaped to fit.

The actual B model tail cone is a clear plastic cone. I am just going to simulate the plastic area and add the two false broom stick guns that Dolittle stuck on to keep fighters back. They even painted black strips to make it look like gun slots. I wonder if it actually worked.

Here it is all assembled as dry fit. This was a very large project attempting to be more scale. It would have been much simpler to just do a standard hinge as per the plan. It will be interesting to see what happens when the flaps are deployed for the first time with plenty of altitude. Now to do the outer flaps to match, could be tricky.

Turret install mostly complete other than filler around the base. I will, in the future, build the gun setup, maybe I can find a kit for the turret.

The restraining setup to hold the turret in position. Once pushed in, the wire hooks under the former to keep the pin in place.
