The Dr1 can perform a skid turn in WOFF. It seems to go to the right better than the left (although that could be my imagination), but both directions are possible. With full rudder application you can change heading as much as 60 to 70 degrees in just a few seconds but it's impossible to maintain control more much longer than that. However if you don't apply as much rudder (maybe 50% or so, I haven't quantified it) you can accomplish a full 360*, and theortically continue indefinitely. It takes a considerable time...I didn't have a stopwatch but I gave up counting at 20 seconds and wasn't quite halfway around. Precisely my experience Sir

8 Gs... incredible, what has been achieved in those early days. Completely without State-of-the-Art Computer analysed Stress Simulations or even a Pocket Calculator.
Believe it or not - they just put sandbags on the main wingspar in tests. That way they found out how much a wing could bear before it would break. Here are some photos from the Fokker company:

One more example for a broken spar. If I get that right, the spar broke under 1000 kilogram. The addition read "septuple". So the wing must have been able to bear "sextuple" the weight.

Here's a free ebook on that very subject. [url=http://www.freebookspot.es/TopTen.aspx?Category_ID=124][/url] http://www.freebookspot.es/TopTen.aspx?Category_ID=124That shows the first page - the actual book is on page 1301 but you can have fun looking at all the others on the way if you like.

IIRC, the original design and prototype had no interplane struts and the wings withstood the forces fine. Pilots' worries about some flutter is what caused Fokker to add them.
SALUTE TO ALL!

Glued?!? What did they use on the lower Wings? Scotch Tape? AFAIK, the panels were glued and nailed together. The main spars of the lower wings were much shorter and maybe didn't break up as easily as the upper one did. Just noticed WOFF has this modelled also

I'm not the aircraft expert but from what little I've gathered over the years, I would say the following. Camel turns faster to the right, DR 1 is faster to the left. Why would this be? They were both rotary engines. Did they spin in opposite directions?
In theory, there is no difference between theory and practice. But in practice, there is.

Glued?!? What did they use on the lower Wings? Scotch Tape? A recreation of the original Nieuport 28 plans showed that the part of the upper wing, where the fabric tended to rip away from the fram in high-speed dives, was improperly nailed/tacked. It was only glued in that certain section, which was the reason for the tearing tendency. Obviously things didn't always go so well when one or the other was skimped. From what I gathered, the standard construction technique of the time was to use both nails and glue to secure the wing fabric. Not sure if there were some rare models that may have done it differently during WW1.
