One of the main things was to get the files all sorted and get some of them converted from formats I no longer have access to as well.In some cases I find it's just better for me to take the 2D .pdf files I have and remake the model from scratch.

I will be happier when I can get back to the Daily branch but it's all good for now.

Are those models from a bigger assembly?

Re: Call for screenshots
Hey Aleks,
Most of what we do in the restoration of aircraft is fabricating from sheetmetal one-off parts by hand. When it comes to parts that are machined either in house or shopped out we make 3D models and 2D drawings to ensure that we can verify design and function. Primarily small assemblies rather than a complete model of the aircraft we do components as required.
We have taken over incomplete projects from other companies and have had failures of components made by others due to poor tolerance control or Q.C.
Here is our number 2 aircraft in test flight:
Our first Me262 Replica slid off the runway during landing on the second flight due to poor tolerance control in the landing gear components that were provided to us "ready to fly" by another contractor. Repairs cost $260,000USD and 6 months. Thank the good lord that out pilot Wolfgang Czia was unharmed in the incident. Me and Wolfgang on the wing at 0:55

Re: Call for screenshots
I was never much interested in (old) airplanes but the Me262 had already impressed me as a boy. There was one thing that always bothered me: It looks as if there is almost no load on the frontwheel. Perhaps you can drop a few words about that.
Did you restore the original engines or are some modern replacements inside?

Re: Call for screenshots
We used "modern" engines in our planes. G.E. engines from the 1960's as they were much more reliable and more economically maintained. We paid about $35,000USD for the first pair of engines we purchased with good cycles remaining, about 1/4 life remaining. Rumor has it that The Flying Heritage Museum has spent millions repairing 2 Jumo 004 engines for the original Me262 they have. Been in work alot of years too.
As for weight in the nose, we installed 475 pounds of lead and 2x 98 pound batteries to make up for the lack of cannons and armor plates.

Re: Call for screenshots
Thanks for the info, so the arms are where the weight in the nose came from.

Another note:
We have to make up for the weight of the cannon and armor for the airplane to fly. We did not add the weight that would have been above that for the ammunition that would have been there as well, another 400 and something pounds.

Workbench - only Part Design and Part - no assembly workbench used. It was rather easy work - only problematic thing was a few casted elements - not all fillets are made because of crashes. But i blame opencascade for that.

I was doing some testing on a tower pc with a ultra wide monitor and thought that Freecad looks just beautiful.
