I forgot to post to the list after my dodgy hexacopter build was completed, so here's a pic of the 1m diameter beast:
Sticky tape, cable ties and a few rivets here and there. Weighs around 3kg with batteries!
Here's two funny videos of me learning to fly at the park. This one gets some nice height on it, and then just lots of bouncing around:
And just as I was getting the hang of flying a wire wiggled loose and the thing went nose first into the ground:
All quite fun!
Now that I have the parts I think I'll build a new lighter/smaller frame to get slightly longer flight time out of it.
