    Hey Planecrazy

    I have used Cad-Kas forconverting pdfs to dxf,and found that this can convert pdfs,that aide pdfconverter cant do,by far the best freeware i hav found on the net.

    The demo version only allowsyou to convert one file at the time,but since most pdf plansare in one fileit doesnt matter.

    Youll have to edit themin somekind of cad program anyhow,becausesome of the parts you needmultipleof.

    A tip for faster cutting is to join as many possible lines as you can in your cad program.

    Sadly not all lines are connected after converting, but take your time.

    i just cutout a T-38 talon in 120% size, and it took me about 1 hourtocut,without the lines joined.
    Bet you Ill cut it in 45 min if i joined the lines

    One is for an F18 Jet and the other is for a Edge.

    Hi Greg, I would really be interested in see what u have done with CNC application for this type of project. My name is Norm and teach at a local high school. I teach TEch Design and use Mastercam, Softplan, etc. I am interested in using CNC milling, and electric planes as a unit of study in my program. Looking at a jet style plane, but must also look at level of difficulty and time restraints. I you could send me some plans or whateveer u have I would certainly appreciate them. Thanks. Norm the doctor.

    First time poster here but have been lurking and learning for a while. Saw this thread and thought I'd jump in with a cnc machine that I've been using with great success. It's kind of new and relatively application specific, but for 3D flat foamies it makes short work of design through finish cut. It's called a phlatprinter (search RCGroups- I'm 66tbird). Its a roller feed with the Z on the Y gantry for a 22x42 cutting area with a 1.5" Z travel. . Sketchup with a Ruby plugin does the code. The kit was put together by another member and offered as kits. My thanks goes out to him and his wife for the work they put into teaching the group that bought units.

    I've cut every kind of foam I've put in it no problem using a .125 rotozip grout removal bit in a dremal 200 on low speed. I've made flat patterns that fold into shape, cut hinge lines, plus more.

    I've been converting files faster than I can build them and now I want to do hardware packages, which is why I'm over here reading up on another type of machine.

    So it's all jfyi.

    Hey guys! Long time since I have written...good to be back. I have some DXF plans on my site. I just uploaded the one below. You will find the download is just a tad bit different. It should be a 100% download and cut...there shouldn't be any work you need to do to it.

    I also just cut out a swing wing f-14 and will be uploading a "cnc router dxf file" for us guys with cnc to use (permission granted by author

    My plane I fly http://www.cuttingedgecnc.com/foamyairplane.htm

    Here is the file to the latest one below.

    F-14 Tomcat: http://www.cuttingedgecnc.com/f-14%20tomcat.htm

    They fly and look awesome.

    Note: I found my dxf files on my site download as code but dwg seem to work... anyone know why??

I also have a dremel multi speed tool i am thinking about making a mount for and using that as it should have enought power to cut thru the foam.

    I have cut several 6mm Depron foamies out on my Haas VMC using a .050" drill bit (friction cut,more clog prone) or a .125 sintered carbide burr (from hobby shop)spinning at 7500. have to play w/ the feed (20ipm range) to keep from melting but I have had good results.
