I'm trying to figure out how to get my flight controller and some other bits mounted in my S800. I'm still trying to figure out what will work, but this at least gets a couple of things out of the way.
I've flown it with this stuff and it seemed to work out pretty well. I've still got work to do on this plane, but I think this covers my electronics needs.
I started doing the work in Fusion360, but once I added the honeycomb, it got incredibly slow. It basically became impossible to work with. I took that as an opportunity to learn openscad better. This is further along than the Fusion360 model and is pretty quick and easy to work on.
The source is on github (and in the files here), so if you want to play around with it, it's there.
