Top and bottom plate is 30% larger than rcexplorer (lightply, coffin shape).
Arms are 12mmx12mm pine.
Motor to CofG is 35cm.
Motors are Emax CF2822 (1200kv).
ESCs are HobbyKing F20A flashed with Simonk
FC is HKV2.1 with V1.6 KK software.
Battery is 3S 2200mAh (55c - so I don't need to worry about abusing them)
Yaw servo is Corona DS-939MG (5 and works a treat)
Props are 8x4
Canopy made out of dense foam packaging
Due to enlarging the top and bottom plates, the front motors sit further forward. Distance between front motors is 55cm and distance between front and back motors is 63cm. I would probably build the next one with standard size plates and make them out of PCM material.

I love this toy. It's mental on scalestick 3! I've managed to fold an arm back quite a few times. Once, the two front arms ended up at 20 minutes to 2, the left arm folded back so far. I still managed to land it which is more of a testiment to the flight controller!

I did have the flight controller mounted on a dense foam pad (with double sided tape). I'v left the foam in place and squashed it down by screwing the fc down to the top plate.
you should have your FC mounted where all the arms come together, or as central as you can. With that board, it should help a bit.
