Here's the quad folded

The flight controller board will have a separate mounting plate that will be vibration-isolated from the main board. In addition, I've ordered another laser-cutting run to make a battery/camera mounting plate to hang underneath the quad, again using an anti-vibration mounting.
If this thing flies well and if anyone is interested, I'll put up the build steps and links to the laser cutting plans... but only if I see some comments from all three of you! :D
