Turtle Report:
The 1/16" steel strap holds the top wing panels together and the joiner/alignment wire keeps the panels from rotating relative to each other. There is still noticeable movement, i.e. the panels separate at the leading edge, but handled carefully this arrangement will allow me to pick up and mount the top wing to the cabanes. All the cabling on this model is functional.

You have really done on a larger scale what I did on my 1/4 N11.
I built a sturdy gun mount for my strapping between the wings...
My homemade dihedral brace box is a little sloppy on the fiberglass dihedral tube I used in it.. when you look at my footage with the camera on the wingtip looking inward ,you can see the wing flex under load.. It moves a bit but I think is very strong. Of course if you have built the BUSA N11 or N17 you know how little is in that bottom wing.
Last time we flew the WW1 I took video and the friend flying the N17 pulled a few to many G's in a corner and you can hear him say "OOOOOHHHHH , the wings FLEXED....."

I've resisted the little pop ups trying to lure me over to windows 10 (the dark side) lol
Art maybe a small steel strap on the underside of the wing, below the spar would be in order to help stabilize things while you're mounting it. A bit of a breeze would make a wing that big a real handful and you wouldn't want any damage .

Art, you need to be mounting hard points for camera mounts ! I expect to RIDE on board that thing... if in movies only !
Not that I haven't already SATURATED youtube with N11 on board footage ! hahahahaha

Turtle Report:
I preformed a lower wing tip and glued it to the wing. It needed a little adjustment, so I wetted it and clamped it up.
We will see tomorrow if it was successful.
Wetted the other tip and clamped it into the form. Watching it dry........
....... to be continued.
Lance, you will have to come to the ODP and tie your camera onto the beast and get your own videos.....

I don't have a clue as to how much horse power is needed ...........
I tend to look at displacement rather than HP. HP ratings are obtained by engine manufacturers by using props which are inappropriate for our application to get the RPM's up which gets the HP rating up. For our application on high drag WW1 airframes torque at a lower rpm is more useful than horse power at a high rpm.
But the more displacement one has, generally speaking, the more horse power one also has (however much that might be).
I think I have enough with 120cc's for good "scale" performance.

Confusion is my fault.
Foodstick was speculating that a G-62 might fly a 1/2-scale DR1. 10 hp is a fair estimate of the required power, I reckon, and should give a good performance ... actually better-than-scale.
A half-scale Nieuport 11 would need about the same, 'cos the full-sized had the same engine, I think ... 110hp rotary.
Your proposed engine is reputed to develop 18hp.

The problem with a G62 is a 22" prop, with a Reeves drive reducer that goes up to 30" or with a Shlundt drive I think it turns a 32 or maybe 34. That might fly it but it wouldn't have any reserve-none-if the need arose. I know of a couple 1/3 scale DVIIs that use the Reeves unit and weigh in the mid 40s, they fly well but performance is limited. Art has the right idea using more cubits and I'd prolly want 150 or 170 but if he believes 120 will fly it then I believe 120 will fly it. You go Art, got a weight estimate on the N11.

Heck yes, Doc ........ some where between 50 and 100 lbs. 
hahahahahahahhhaaaa
Early on I was thinking 65 pounds. I have not done any real world weighing of the pieces and parts as they are fabricated, so I don't have any update on my estimate, but I suspect it will go higher than 65. Maybe I'll do some weighing and see what it looks like.
I think that a G62 with a reduction drive would fly the model, but would be under powered for normal model flying purposes.
Shoot, Doc might be right and I'll need a 150 for it. I have seen a 150 fly a 1/2 scale DVI at over 100 lbs. - it was safe but at the middle to lower end of the power requirements.

The "half-scale weight" of the Nieuport 11 would be 75 pounds. That represents the fully-laden full-sized aircraft, at about 1200 pounds.
At least, that's how I understand things, because at the scale speed, you will be developing only 1/16th the lift of the full-sized aeroplane.
Obviously, it'd be great if you can keep it a bit lighter.

As it stands now, there is almost no way to remove any weight other than re-designing and then rebuilding various parts of the model.
I have a certain set of goals for this model with flying well at the top of the list followed by simplicity of build/field assembly and a substantial enough structure to resist most rough handling and hangar rash. Oh yeah, don't forget that it needs to fit into my Dodge mini van. Design is interesting and in most cases is certainly a game of give and take.
You're right bogbeagle, lighter is always better.

I don't know what kind of formulas you are using to do these calculations, but 75 lbs. would be a good weight for the model.

Gosh, I hope not ...... I know for sure that is not in this year's budget! (or any year in the near future for that matter)
On paper, Joe, it fits just fine ......... ok, ok .... ok then would you believe it fits, BARELY! I have test fitted the fuselage and that just does fit. The cabanes will have to come off because of the overall height. I am sure it will fit.
Well, at least that is the plan.
