Second iteration of the Quadra-Pigeon. 
Longer, hollow arms. 
Rubber mounted motors. 
Rubber mounted control board. 
Electronics protected by a cover. 
All the old camera mount stuff is scraped away. 
Lots and lots of small changes. 
I finally gave up on using Sketch up. I was spending the lion's share of my time trying to overcome weird issues and not moving forward on the model at all. This was a good project to get better acquainted with Solidowokrs, so that's what happened. This machine is all modeled in Solidworks. 
I have the airframe pretty much the way I want it. Next is to design a gimbaled camera mount.
