Thanks to all for joining. After parts inventory had to do some preliminary work. Build the receiving boxes. These are built from lite-ply. Had to wrap the aluminum sq.tubes with wax paper then build the box around the tubing. Built 2 sets of 4 sizes. Then the top wing is a 3 piece wing. The joining ribs needed to have a lite- ply rib laminated and predrilled for the trailing edge 3/8 dowl. All ribs were center punched for hole location.

The 1st kit built 1/3 scale Dva to fly was built by Warren Cross(HIGHLY experienced builder, many BUSA kits). I had the privilege of maidening and then putting a number of flights prior to a few at "Warbirds Over The Rockies"(see their video).
So, here's some advice: the airframe is well stressed for POSITIVE "Gs", but NOT negative! Definitely strengthen the fuselage where the spar goes through. Beef up the firewall/motorbox area. Your going to need noseweight anyway.
The flying wires are CRITICAL to the airframe. Use high quality hardware.

VG, yes it's a 3 piece wing. The first pic is of the top mid wing. I built the 1/3 Fokker DVII and the wing tubes were built the same was. For the Albatros the difference is build split boxs, the 7 you built the box and cut them in half for the wing tubes.
Pattunt thanks for the heads up. Looking at the leading wind d shape, i see there is only sheeting on the top of the wing. Think it would be something to think bout to sheet the lower part of the leading edge wing also. We were talkng bout doing this a few day ago. Just didn't want to add a bunch of weight if not needed. Thoughts any one.
Top wing receiver boxes installed. I had enough room on the backside of the box to install a 3/32 x1 to reinforce the boxes.

Center section cabine hard point, t/e dowl and laminated vision cutout completed. Took the advice of manual and added the hardpoint piece where the tee nut will not protrude through the bottom of wing. The vision cutout , the manual gives you 2 way to accomplish this. There is 4 of these to laminate, all at once or set the first one the add each one till completed. I chose to do the one at a time. Seen to give me better control of the process. Build is going great and having fun with the build.

Welcome cocobear..thanks for your input. I'm having a blast with the project.
Wing tip installed, you get to makw a jig for the swoop in the wing tip. Didn't take no time at all. Moving to sanding the leading edge to make sure it all nice and straight.

Dave This is the color I'm thinking about. Red on top and light blue on bottom. I think it would look good if I did the panel lines on the fuse, wood grain varnished. I have not looded at any 3 views yet for that detail. Might be a few days before the airforce museum opens to pick up so good documentation. Any help in this matter would be wonderful. Thanks

Very nice work. It seems the only difference between 1/4 scale and 1/3 rd is the distance between the ribs! As much as I would love to build a 1/3rd, I just do not have room to store the thing or transport it. Having seen the prototype at the WBOTR last year, it was very impressive. Somewhat envious of your en devour, but I have to admit I would build the big Fokker D7 .
first. None the less, I will be watching this build closely.
