I've recently been busy building the new 'headcrab' quadcopter rather than fixing up the ol' X600 frame... The deployed frame is starting to take shape, with motors and ESCs (four yellow bits with all the wires coming out) mounted and connected up.
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
