Mini Quadcopter

I have created this because I wanted to design a quadcopter for brushed 8520 motors and the SP3 Racing F3 Evo brushed, which I can fly indoors. I also designed a propeller protector. This version is flying pretty good in my opinion, where previous versions (with smaller arms) where quite shaky.

I have printed it in PLA and ABS, but only tried out the PLA version so far.

When using the propeller protectors, it is currently not easily possible to mount a camera so that you have free sight (some protector structures are in the way).
