I have started in a cost effective way!
I present a used Turnigy Micro Quad, with an upturned plastic container with cutouts to fit over the KK2 board, receiver and HK wing cam HD (720p). It's squishy in there but it will do.
The whole lot is sprayed black, mainly to hide the 'used' look and the recycled plastic container from what they really are.
I did all this without ever flying it, because I didn't have my Spektrum DX6i yet. In the meantime I have got it, following a frustrating adjustment at the weekend, all I managed to do was ascertain that one of the ESCs doesn't work and that even these little ones can be dangerous beasts. I accidentally launched it with the remaining 3 motors at full stick into my face. Luckily my hand got in the way and all I got out of it was a broken prop and a small cut on the hand.
The saga continues.
