Show us anyting you scratch built (your own design or plans is fine) using any combination of BlueCor, Fan Fold, Depron, EPP, or any other type of foam I forgot to mention.
Here are my 3 so far, still have a whole stack of FFF left.

Here's the only one I have so far. It's made from a Simi-air 23" N9M foam chuck glider wing. The booms, ailerons, vert & horiz stabs & elevator are made from laminated balsa sheet. The fuselage is made from a piece of styrofoam from a food shipping container. You know , the kind that perishable foods come in when shipped across country. Those containers are very good quality EPS. It's running a Feigao 12 X 30, 4200kv brushless motor with a BP 10amp ESC, 2 HS-55 servos and 1 Blue Bird 303 sub micro servo, a 4ch Blue arrow Rx powered by a 450mah 3 cell, 10c LiPo battery turning a GWS 3X2 prop. Weighs 6.8oz and is quite a blast to fly. I have another CAT project on the bench using an old sky scooter wing and similar building techniques. Both these projects were/are built using the LAR, (looks about right), method. WIll post a pic when the second one is completed and flying.

I am presently working on an X-29 from 3D foamy CD. If u are thinking of doing this baby, be forewarned that the intake and fuselage tops are incorrect on the pattern drawing. U should trace or make poster board patterns from the assembly drawing. The FA- 18 was my first Depron foamy, built from a kit.

"Delta Rocket" blucor with a balsa sheet sandwiched nose. Really moves and modeled after the simple paper airplanes that every school boy has made to throw around the class room or are they considered weapons these politically correct days?:D

Here's a little sorta P-51 styled foamy. Ws is 28" Length 21" RTF Auw 6.25 ounces GWS IPS-A power, and GWS micro electronics. Flies great in calm or near calm weather. It was sized up from a stick and tissue free flight plan off the Net. Foam is sturdy board core from Hobby Lobby (the craft store) I have found the paper comes off real easy from this brand of sturdy board and is great to work with. The foam comes in 5mm and 3mm thicknesses.

Up in post #2 I posted my little, 23" WS, scratch build cat & mentioned that I had a larger cat I was working on using an old sky scooter wing I had laying around. Well here she is and and she flies quite nicely.

Here is a pic of my scratch built biplane from plans from 3dFoamy. I added my own G-force style wing skins. It flies great.

I just made a flying wing, out of left over sky scooters wing. I powered it by a 400 and Nimh pack but that was just to see how it flys. I changed the wing a little and it's very fast, even with speed 400. I'm looking forward to put a 400 size inrunner in there, and a 3S lipo.
I changed the bottom too to fit in my cells.

Here are a couple of pics.

Here's a shot of my latest scratch build, it's my version of the seawind, it's still under construction and took a nasty nose crash on it's maiden but it fly's pretty good once in the air

Here's a couple more The first is a Nasty with a modified wing design and the 2nd is of course a F-15, originaly built with twin RDF but wouldn't fly so it ended up with a stryker 480 motor and 3S lipo

Here is my first try at working with foam.
It is patterned after the Kaos, one of the pattern planes of the early 70s. Made from foamboard, 37" span, geared speed 300 and nicads and weighs 17 oz. A very fast flyer but don't have the flying space to explore its full potential yet.

I built this Gulfstream IV SP by scaling up a 3-view drawing directly onto the BlueCor fanfold material. 45 inch span, about the same length, two GWS EDP-50XC DD with 3/2 (or 3/3) props, 2S 620 LiPo, rudder, elevator, throttle, and ailerons. Flies nice and slow with 3.92 oz/sq ft wing loading. 9.5 ounces flying weight. 2nd indoor photo by Kirby Pople.

sr71fan,

I like it! Did you do a build thread on it anywhere, or do you have anymore detailed photos of the build?

Omaha,

Did not do a build thread. All pretty basic profile construction. One unusual aspect is that the engine nacelles are glued directly on the side of the little motors. By the way, this plane is NOT overpowered, but flies very well in calm air. Two wings are shown because I first flew it without ailerons. Sullivan Gold-N-Wire flex cable is used to actuate the elevator. All hinges are over-and-under Scotch tape method. Hand launch and recovery is very easy because of low-speed capability, so I decided against any landing gear. Here are a few more pictures, including test glide without radio, and a flight in the gymnasium...

Thanks for the extra pics! Is that balsa tri-stock, that you are using on the wing and H. stab? Don't you post quite frequent at RCG? I think I've seen some of your other planes and/or post, over there before.
