Ok, ok, so quite a few of you have build Zepron planes and sent me pictures and other info to include here, but unfortunately I haven't had a chance to add them to the site. Please check back later ....
In the meantime, here's Yann LeCun original "ZMF" (Zepron Micro FunFly):
If you've been "rolling your own" for a while you've probably noticed that bad results can be even more instructive than good ones. I know that all of your designs "fly off the board" every single time but well .... if you happen to know somebody else who didn't take advantage of your design wisdom and built something that's not quite as wonderful as he'd expected .... I suspect that most folks would still be interested in seeing any not-quite-wonderful experiments your friend (or you) (:-) might be willing to share.
Depron Links
Links to Depron pages. As you see there is a whole lot of material and lots of good ideas already published out there. Some of the designs are very large size and some are quite small, but "the spirit of the foam" is to just look at what you like and adapt it to whatever size, shape, etc, etc you're working with.For instance I'm not a very big fan of the 2.4 gr servos but there are some really cool, really small designs on the Klaustrophobia site that use these. Problem? Not really, just make everything a little bigger and use the superlative HS-50 servos.
On the other hand, some of the planes are larger or are built using thicker foam. One of these is the Drenalyn which is too large for a single sheet, but fortunately two sheets can be joined at the center-line rib to make one. For some other planes that too large similar minor mods, or else, scaling them down will get things going.
If you have any links that should be added here please let me know.
We start off with Yann LeCun's 2 pages that show Depron planes and Even More Depron planes (as well as a simple FF hovercraft, robots and other goodies).
More French Flying Wings at the IXIR Pages. Unfortunately they're too large to be built from Zepron unless you join pieces together. However, they have some neat diagrams that show a technique to layer pieces together to build the planes that's useful to see.
Patrick Wegener's Klaustrophobia Website is probably the biggest and "baddest" (:-) of the all with tons of How-To Info, lots of Pictures and the original version of Michael Bohm's "And Now" indoor flyer.
(The Dep Design page also has other changes and versions of the "And Now".) The Original, the One, the Only, ladies and gentlemen, we give you... (ta, daa...)
The Pibros Unfortunately this one too is too large to build with Zepron, but it's still an interesting site.The "Big Bee" is a built-up high-wing design that's ideal for Zepron.
Another giant (also German) site from Kai Huber with foamies, slowflyers, electronics and more.
Pilatus Porter from Depron that would also be excellent for "translation" to Zepron.
Und Nu review and other data but this time in English thanks to Trevor Hewson.
The Aeronutz site has lots of great stuff (and it's all in English) (:-) including Twin Motor Steering for lightweight foamies, Working With Foam and more.
Really neat FF Flying Wing. This one is also from the Aeronutz site but it's different enough that I put it by itself.
Polish site with several Depron Designs.
An Italian site with lots of really neat planes including Fantastic, Eurofighter Pusher, Drenalyn Flying Wing, a neat Aermacchi AM-3C high-wing trainer, and lots of other stuff. There are not a huge number of pictures for all of the designs, but all planes are neat, and the pictures are very good and show plenty of detail to easily let you build any of these planes.
Another Italian website belonging to Maurizio Martinucci with several excellent electric models from mixed Depron sheet and polyurethane foam blocks. Of particular interest are the F-86 Sabre where you can see the structure of the 2-surface foam sheet wing, and also the A-10 Thunderbolt page that shows a different type of mixed sheet / block foam wing.
For a slight change of pace, a German site showing an electric hovercraft built from foam sheet. It's in German but with lots of good pics that tell the whole story.
A great British website from Steve Webb showing several of what he calls "Depron Dooberies" like his Dubbel Trubbel twin, Pain Cone and Ladybug. Lots of other good stuff here also.
David Thunissen's site showing his modifications to the "Und Nu" slowflier. He also has a a small .pdf plan. It's not full-scale but it includes all the measurements and you can easily build your own "And Now" from this plan.
