I have just finished the design and prototype phase of my open source quad frame. Its a 1.5mm G10 frame for 10"-12" props. I am in the process of designing a two axis gimbal for it, but to do this i need access to a faster prototyping process. I have entered the instructables shopbot contest and I really hope that i can win that as it will make prototyping so much easier. I've spent approximately 3 months on this design so id really appreciate it if when downloading the dxf you can vote for my instructable.  

The DXF is on the third page http://www.instructables.com/id/Quadcopter-frame-design-fiberglass/

Features 

The design is made up of a very secure "ball" that protects the electronics and attaches the arms, making it extremely crash proof.

The arms are reversible so you can fly with some up and some down at the same time as the thrust line stays the same.

ESC's have their own mounting boards.

Motors lie inboard of the arms for protection.

Large battery bay with strap holes.

Large electronics platform.

The Design is fully modular for easy replacement of parts.


No glue is used only bolts for easy assembly and changing of parts.

Extremely strong and high GPS board. 

A gopro camera can mount directly to the top or bottom.

Sonar mount on landing gear.

Have fun with it 

Chris

Great design! Will you be selling this as a kit or can you recommend a place that would make the parts. I don't have a CNC machine… yet :)

Comment by Hans Miller on January 28, 2012 at 5:22pm

I love it... Have downloaded the plans and will be pestering my local cnc shop shortly. Well impressed with you...

aren't the arms on the back upside down?

Comment by steve F11music.com on January 28, 2012 at 6:04pm

It looks like they are and seems it can be configured that way. Probably even with some motors upside down. Would be interesting for testing different flight configurations or even octo by putting two motors per arm.

The quad can fly with the arms in either configuration, as the props lie on the same level. This make a really cool looking quad in flight. It also helps for camera rigs and orientation.

In the video on my instructable you can see it flying with two up and two down. ;)
