This is my back up quad to my Chameleon, although I seem to fly this one more. The top plate is aluminum that a friend of my came up with. It has been very solid so far.
Wow really cool! He made that top aluminum plate for you? That's preatty awesome.
the aluminium plate is awesome, you are the first one that I know that use that on a drone. I did some design but never actually made them real. I believe it has potential in frame design. Nice work!
