UPDATE: The frame is now built out of 10mmx12mm timber & weighs around 30g, I also changed the FC to an arduino pro mini with gy521 breakout board, the motors are still at 1900kv but with a delta termination this time so the copper is really packed in there . This is how it turned out in the end but I don't have any recent video of it, one of the motors was loose in this (old) video so it was not flying right at the time.
I do like this setup, nothing is overly stressed out & it gets a decent flight time. In static tests each motor was drawing around 6A from the 10A esc's, im guessing its a bit lower in the air. The lipo's always come down quite cool & have had plenty of use with no puffing etc.

These are my first proper steps into the world of multiwii.
It took a while to loose the vibrations & get the board setup right, it still needs some fine tuning but I think I will build another lighter frame using either thinner wood or maybe carbon rods. This frame is a little heavy but crashes well .
Its been feeling a bit gutless recently & may be due to a motor mount not being totally straight anymore.
