Blohm & Voss P.179


Creating the unique profile of the Blohm & Voss P.179 wing tip (above left) is covered within the plans and requires cutting a section of the tip from the foam core wing panels. A piece of scrap foam is then glued to the tip and carefully


But a much too steep hand launch taught me that the plane should be tossed out lev- el, not at a high angle, so that it can gain some speed before being thrown around. Hey, it’s different, attracts some attention, easy to build, and it’s fun. For more infor- mation on unusual German aircraft designs made during World War II, the web site is www.luft46.com.


It’s well known that sheet foam airframes


can provide a lot of flying fun at a low cost and they’re easy to build. This one I consider a hy- brid construction; rather than a flat sheet foam wing, it has a hot wire cut foam wing with a thick symmetrical airfoil along with sheet foam for the rest of the parts. I did this to get better windy weather flying capability


carved and sanded to shape. Text has details on purchasing foam wing cores from a few sources. The aileron surfaces (above right) are easily fine tuned thanks to the straightforward layout.


and I like the way they fly, think it’s a good technique for fun scale profile warbirds. If you don’t know a local friendly hot wire cutting foam wing core guy, go to The Core House http://home.earthlink.net/~ philcartier or con- tact Bob Hunt at Robin’s View Productions robinhunt@rcn.com.


There are different sheet foam materials available for this type of building, and I pre- fer BP Hobbies’ construction foam as it hinges easily with plastic packaging tape, paints easily, and is repaired easily, after those crashes caused by wind gusts and ra- dio glitches. I cut the sheet foam parts out with the aid of a metal straightedge and a sharp scalpel-type modeling knife. The 1⁄32- inch plywood nose section doublers add a lit-


tle weight but also add a lot of strength. To stiffen the rear of the fuselage, a carbon fiber tube or strip of basswood or spruce will work. If using a strip of wood flush with the sheet foam, an added ¼-inch square strip of wood on each side will help even more. I build with fast drying epoxy which sticks well to most foams, but the types with thin plastic covering on both sides need a lot of small holes poked through the plastic where the epoxy will be going. A friend uses foam compatible CyA glue where I use epoxy, and his airplanes always come out lighter than mine.


The wing spars are 1⁄8 x 3⁄8-inch basswood, available at hobby and arts and crafts stores and epoxied into the wing cores. To get the
