Open Frames by jbkappirossi, MikeH, Kristjan, A*Morale, Snagglesworth

Okay, people have been asking me if I could do some custom frames. I have no problem with that and this way I can contribute a little to the OpenPilot community as well, because I don't have much electronic nor coding skills, so I thought I could just post this online for everyone. I will do a few more and if it's not too much work, some custom jobs as well, think by that of motor hole's, FC hole's and even some minor changes to the frames itself. Some input and feedback will be highly appreciated.

Not all will be tested! If you are the first who orders a frame it might not be what you expected from it, So i will put Prototype above it, so no-one will misunderstand the risks of it, because I am and will not be responsible for it.

Frames that other people drawn are also highly welcome, but they will have to be fully done! Send the DXF file to me and I will post it in the TS. My mail address is jbkappirossi@live.nl

It would also be very appreciated if people can help finding shops with the parts needed for the frames, like; nylon screws, standoffs, even G10 sheets, Carbon Fiber, etc. I will put up a list for that as well. So we can all get a frame as cheap as possible.

Please, if you have questions about what motors, ESC's, etc. to use on a particular frame, just ask.

Final, it would be totally awesome if there are people who are willing to help out with CNCing. It doesn't have to be free, but think of it like this; I'm giving away my drawings for free and it costs me a lot of time!

Warning! There need to be made pockets into the arms, half the depth of the total thickness of the arms, so they fit into each other (look at the screen below for reference).



I recommend that you cut the frame out of Carbon Fiber only! 
G10 is not only heavier, but at the same thickness the tensile strength is probably half.

Carbon Fiber

arms 2.5mm
frame plates 1mm 

G10 don't know.

- 20 * m3 plastic or nylon bolts.

The Template 'DIY flat Wooden Arms' consists out of the original sketchup .SKP file as wel as a .DXF and .DWG File.
You can download google sketchup for free or a dxf/dwg viewer witch has a function for printing.
I've showed in the video how to print it out with sketchup, so you can glue it on a piece of wood witch makes it very easy to cut over the lines and drill the holes in the right place.
