My sheet foam cutting table is just clamped together, consists of a sheet of 1/2" plywood about 18" X 24". 1" X 2" lumber clamped on each side as rails to guide the sheet, and one along the bottom front to square the surface. A 3/8" hole holds a peg to secure the cutting wire on one side and a guitar tuner for tensioning the wire on the opposite side. An old HO train set DC transformer for power. The cutter is .010" piano wire.

And the plans printed out, cut and taped together to form a single large sheet to build on.

Man on a mission!

It's funny how all sheds and garages for us modellers the world over look the same...

Here, the the page from the PDF containing the fuselage formers has been assembled and pasted to the foam sheet and the formers are ready to be cut out. Two of each is required to complete the fuselage.

Giuseppi,

Subscribing!!! The thought has crossed my mind of trying an old Comet, with 2mm and 1mm depron.

In this image, the plans have been layed out on the building board and covered with wax paper. The bottom keel has been cut from the full sheet of foam and pinned to the building board over the plans. The formers have been notched to fit the keel and glued in place. The glue is an aliphatic resin thinned with water.

Here the fuselage side keels have been cut from the sheet and the wing templates have been glued to the foam sheet.

The plans call for a built up wing with ribs and spars, etc. This model will sport a flat foamie wing with Jedelsky-type airfoil.

Okay, plan B...or C or D. Whichever it is. I've scrapped what I had done and will be starting over.

I should have been building flat on the plan one side at a time but thought I'd try something different.

Anyway, the way I was going was like, no-wheres-ville daddy-o. It looks a like a trip to the balsa wood store is in order.

I'm determined to do this by hook or crook.

Well, I got re-started. Or maybe re-re-started. I've lost track at this point.

The thumbnail shows the top and bottom keels pinned to the plans with a sheet of wax paper in between.The first three starboard formers have been glued to to the upper and lower keels. The foam sheet the keels are cut from is Dollar Tree foam board cut to 2mm on hot wire cutting table.

The formers, believe it or not, are cut from the top and sides of a foam carton from a dozen chocolate covered marshmallow easter eggs. The foam cartons are very rigid, probably from the label/coating. It reminds me of the GWS foam wings, whatever it is.

I'm not entirely pleased with the way the stick build is going so I'm changing again. The foam keels are not stiff enough, for one. Secondly, the fan nacelle and fuselage will be easier for me built separately. And the formers weren't cut as precisely as needed be.

It's one of those wish I knew then what I know now kinda things. But I had to experience it to understand it. If I decide to go back to the stick frame I'll use balsa entirely.

Here are pics of my latest attempt. It's a card model converted to PDF, scaled up and printed on the home printer. The parts were cut from the pages with scissors and individually mounted to Dollar Tree foam that has had the paper removed from both sides. The parts are roughly cut from the sheet and trimmed to final shape with a drum sander and sanding blocks.

Image #1 is of the formers all cut to final shape. The frame in the background I'm saving, just in case...

Image #2 is the fuselage parts mounted to the thin foam sheet made on the hot wire table. One piece is removed from the sheet and partially formed.

Image #3 is my drill press set up with a small drum sander for truing the formers to the template lines.

Hi, Al.

These are the parts I'm gonna use. I might use this motor instead: http://www.hobbyking.com/hobbyking/s...idProduct=6551

Receiver - DSM2 clone from Target Hobby; Fan - 30mm blue housing and GWS 6 blade from HK; ESC - HK 6 amp Motor - Turnigy 1220 brushless inrunner from HK; Battery - 2S 180 mah built from Zippy bulk batteries from HK

The GWS 6 blade rotor was trimmed to a 3 blade after one of the vanes snapped off. Also, I chucked the EDF housing in my mini lathe and turned down the flared lip to fit the nacelle.
