Ever needed an excuse to start building Lego again? Now is the time! Turns out Lego bricks can be used to build a perfect symmetrical frame for your quadcopter! And... it's super cheap.
I used Lego Technic because it has holes in the bricks. You can mount the motor's with tie wraps through the holes and it's an ideal weight reduction. For the motor's and flight controller I used parts from the famous Hubsan X4.
Interested...? Then dust of those Lego bricks and start building! Or get the complete kit at kitables.co. It has everything you need to get your Lego quad in the air!
