shackspace resident hacker Robert is at it again. This time around he’s built a new frame for this quad-copter.
In the past he’s used everything from aluminium, carbon fiber to 3D-printed parts to build his copters and had mixed results (one 3D-printed copter melted in the summer heat while stored in his car).

Now he went with an all-new plywood design. The whole thing only weighs in at 167 gramms and - despite being assembled without a single drop of glue - is very sturdy.
