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.

The wing nut well allow for easy tightening and loosing of the arms for transportation, storage, also it well give, if there is ever a mishap.

On my last ECHD quad, i glued the arms directly to the 6''x6''ply. It was pretty darn tuff, i used the new Gorilla Super Glue. Boy is that stuff strong. Sets in about 30 secs and is crazy strong, its light and drys clear.
