Status: offline 		Finally back to work. Things got to busy and I had to take a few days off on this. Today I got the tail surfaces faired in and put in the hard points for rigging and completed the frightening task of cutting out the cockpit. I am hoping to complete roughing out the cowl prior to the Patriots game! Go Pats!! I will try and post more pix tomorrow.

Status: offline 		I'm really enjoying seeing this build. Keep it coming!

Also liked the pics of your prior project with the homebuilt engine. Great stuff.

Seeing this WW1 stuff makes me think of the N28 kit I have hidden out in the shop!

Thanks for showing us your process.

Status: offline 		Hi Dave- I'm afraid not, but thanks for your suggestion about appraisals. I was able to get one a hobby professional out here on the west coast and we were able to come up with a fair valuation. Now I'm back to building...

The Albatros looks great. I'll be watching...

I finally finished the blasted ailerons. Aligning 5 hinges is not easy. I used a brass tube through the hinges to align them. Then I attached them to their blocks. I then
glued the blocks into the trailing edges. The hinges then get glued to the aileron. You would think that would do the trick but I still had to adjust the hinges quite a bit to free up the ailerons.
Well at least it is done. I have attached a couple of pictures of the aileron hinge build up and a mock up of the parts I have done so far. The hinge picture shows the hinges alighed on the
brass tube. I think a carbon arrow shaft might have been better. The brass tube was easy to bend and not perfectly straight. I attached the stab so I can work on the elevator. I
could not resist putting the gear legs on and putting on the upper wing. The second picture shows the result. Starting to look like an airplane.

Status: online 		Can you post a photo showing how the strap hinges are attached/built into the ailerons?

My understanding of how these work is that the hinges are slipped onto a dowel that will become the ailerons (or elevator of rudder) leading edge. The hinge collar rotates freely around the dowel with the strap parts extending forward. The when it's time to mount the aileron's (after everything is covered), it's a simple matter of bolting the straps onto the wooden block supports in the main wing. It doesn't seem like alignment would be an issue since the hinges are aligned by virtue of being built onto/into the flight surface leading edge.

But this may be a different technique than I'm familiar with. BTW, I love the idea of strap hinges and I'll certainly use them on any German model.

Status: offline 		There is an aluminum tube that rotates inside the strap hinge. That tube is glued into the leading edge of the aileron. One can also build the leading edge of the
surface from a dowel and slide the hinges on the dowel. I am going to use the dowel technique for my rudder and elevator. The dowel should provide automatic
alignment provided the dowel is straight. What I found with the ailerons is that the straps are free to rotate on the axis of the screw through the block. This can
cause a slight alignment problem. The problem is more pronounced in the case of the double strap near the ailreon control. I have attached a picture of that installation
on Dave Johnson's airplane.

Status: offline 		More progress to report. Dave J and I got together last weekend and did some metal work on the landing gear and the cabane struts. I have also framed up my
rudder and elevator. Pictures below show some new stuff. First off the fuzzy picture of the end of the landing gear strut and the brazed on bits and pieces. Next
is one of the soldered on detail pieces for the wing struts. I put in a picture of Dave J's dummy engine as it is so far. Dave formed cylinder halves from plastic.
The rest is bits of ply, tube and dowel. The next picture is one of my framed up tail. I still have to sheet the fin. Last shot is one of Dave J's cowl. Things are
moving along nicely. I try to do something on the plane every chance I get. This morning I put some cap strips on the wing before going off to work. Dave J got the
Glenn Torrance lozenge fabric the other day. That is the next real challenge. I think it should come out great in the end. I am thinking of covering the rudder first.

Regards,
Dave S.

Is it from your own plans?

If I could build them that fast i would be having a new career job.

Status: offline 		I'll come back in an hour or two and have a look at the next SEVERAL first class models you build. Is the Gotha a foamie? What's the power system? What did you do for plans, and are they included in your 1-1/2 hour?........John
