I say Go For It!  A friend of mine used to build WW1 aircraft for wargame use.  He built some beautiful scratch-built models (at a much smaller scale).  I do want to ask why 1/20th scale?

Because that is the scale of my scratch built Eindekker.

Although the Gotha will be mostly plastic ,here is the Eindekker in the construction phase.

I was just now doing the math. Yep, almost four feet (1.18 meters). Sure you can build it. My own challenge with larger scale models is that the engines turn into time consuming projects, but hey it's cool.

Gary, decimal scales are really easy to work with when scratchbuilding, in particular if the subject was metric to begin with or old drawings are dimensioned that way. By WW1 Germany had made the metric system compulsory.

The Gotha 5 had a wingspan of 23.70 meters. Divide by ten; 2.37 meters. Divide by two; 1.185 meters or 118.5 cm. Easy to do in your head.

Nice project, Philo! I want to see working bomb drops!

Are you planning on using dope to paint your Gotha?  I tried it on a wood framed WW I aircraft hangar and it tightened up nicely!  It also gave the tissue paper a smooth finished texture.  For that kind of size, RC airplane construction makes sense.  So yeah, why not do it?  Like the fictional band from the movie "This Is Spinal Tap", your model scale does not stop at 10.  It goes to 11.

Well I am making the wings out of  3 or 4 ply laminated plastic sanding to profile and adding styrene strips to the wing surface.I plan on using  a trick I learned about 40 years ago to use hex grid paper and carbon  paper to do the cammo.then use a fine brush to fill in the hexes over the base purple color.

Hi there. Am I right, you decided to build your own project (model)? It is so hard to prepare and to plan everything. My respect Yes

Philo;

 I want to say sir; I am glad to see you have adopted a child's assembly toy for braces and clamp surfaces. Being a TEX-LUG ( Texas LEGO user Group member) I use the Bricks a lot :

    I also use COBI,BRIK-TEK and MegaBlocks as well as LEGO .Brand here is a moot point , usefulness is the key.

Yes I decided to cut slots in the bricks to hold the wing formers,seems to work well!

I decided to use 7/32 brass tubing as the leading edge of  the wing.

Had to carve the wing end out of red oak.Had to lace the lower wing to the brass tube with a .10 guitar string.I will conceal it as work progresses.
