RE: x230 Mini Quadcopter
While I wait for my flashing tool to arrive, I made some modifications to my EPP frame. The KK2 board was dropped lower by removing a set of nylon standoffs and I moved the Spektrum AR6100 receiver between the top plate and unused ESC board. The area provided a great place to hide the wires too!
By adding a small EPP frame around the top center area and some legs underneath, I can drop the x230 from any angle without hurting the components.
I'm surprised that there are not more designs that utilize a foam frame for safety. The frame not only provides safety for the quad itself but for the people and objects around it. As far as I know, only the Parrot AR.Drone and this rather large quad frame below at HK utilize this method. I was hoping that we would eventually see a production version of Rolf's "annoying mini UFO". An optional EPP frame for the Turnigy Micro Quad would be very cool!
