Thanks guys. sp, I started paper models after seeing Dan's (NinetythirdLiberator) build logs in the paper model section of "Under Construction" here on the forum. I would suggest checking those out, as you will learn much and the models are really cool. There are also links to Dan's YouTube site in the Nie.24 and recent Pfalz D.III logs, and his video series are very helpful in learning paper techniques for these kits. There are also some general YouTube tutorials on various aspects of paper modeling if you poke around.
While there are many paper model "kits" of WWI aircraft (a google search will yield the sites), I got the "Models by Marek Matt77 Repaints" version of this kit as a download through internet purchase. I copied the downloaded files onto a thumb drive and took it to my local OfficeMax copy center and they printed it out on suitably heavy paper for about $3.00US. I think the download purchase was around $5.00 to $7.00. I cannot remember the weight of the paper, but I recall that Dan mentioned it on one of his build logs, maybe even his Berg (with a different scheme, the colorful Austrian Hex lozenge--I have that one in the stash too). I think the paper I'm using for the Berg might be just a tad too heavy for the small parts, so that is something you can experiment with.
I have both traditional pre-printed paper kits and downloaded kits that I have had printed at OfficeMax. It just depends on what aircraft you want. The Models by Marek or Matt77 Repaints used to be available at a site called E-card Models, but that site is being revamped, so the old stores are not all there. I think Matt77 has a store there again, but I do not know if any kits are posted for download purchase yet. You'll have to search a bit and see what you can find.
Good luck, and definately give it a try. It takes some getting used to, but it is really very enjoyable.
Best regards,
Bob
