    So as I have talked about in another thread I have been working on designing a 20cc sized Giles 202 profile. The goal is to have a profile that will still perform well at low and slow like most all slabs like to do but I want it the wind up tight and carry energy unlike a normal slab. Most if you try to do a poptop will barely get 1 rotation at the top before you have to fly out of it. I have taken what I have learned from a couple other buddies designs and the edge profile that I helped design to get here. It will have airfoiled ailerons not flat plate like most profile. Decided to go this route for strength. Even though I know its going to be more work building the wing with them in the long run it will be worth to not have an aileron that is flexing and twisting under the load of higher energy flying. Originally I had a buddy draw up the wing for me in DevWing so he gets credit for that and I just recently learned CAD. Before I was drawing it up on paper but now that I have this awesome program at my disposal why not use it.
    Here are the specs.
    Wing span 62-5/8"
    Lentgh 56"
    Wing area is just shy of 1000 sq in
    Wings will be removable with 3/4" and 3/8" tubes in it
    1/2" thick fuse
    DLE 20 on the nose
    Solar 771's all around for the time being as its all I have on hand.

    Plans printed. 34' wide paper 185" long. they look nice. I see a few things I need to address with double lines that I couldn't see in the program but on paper they show up really well. I will build from this set though and once its flown make any changes that need to be made then it will be ready for others to build. Drew it up with all the parts laid out on 36"x4" sheets incase someone want to CNC or laser cut it.

    Woohoo! I would absolutely love a copy of the plans if you are willing to share!! FWIW, if you run into a problem with AutoCAD, let me know. Use it quite often at work. Just don't ask too many questions regarding 3D modeling, ;).

    I appreciate it bud. Been struggling trying to properly convert it to a PDF for when it's time so I may hit you up when I get closer. Some of the double lines I'm seeing are where the wing portion was generated by the devwing software and then converted to a PDF. I used the import PDF feature and it got most of it right but some things where off like double lines in places as well as on some of the ribs it drew the chamfers on the lightening holes facing in instead of out. I'm getting better with the program but currently I have prolly 10-12 hours just in drawing this plane.

    Can you export the devwing in a dxf format? Happy to talk offline as well. Will PM you my email and contact info.

    Yeah that's what he exported them too but when I opened those in autocad it would not let me ungroup parts so it was a pain to lay parts where I wanted. I got it figured out now.
