I put my Quadcopter in a few weeks ago. So had to build a new one.
This time wanted folding arms, the arm broke on the last one,resulting is atotalled frame.

I highly recommend it

So back to the build.

Cutting eight 2'' blocks, i glued 2 too each end of the arms. Giving enough area to mount the motors later.
