I wanted to 3D Print my own quadcopter and i wanted to use a different approach than what most others used. I wanted to create a design that enclosed the electronics. I also wanted to try to use more curves and less "rectangular" design that i had used with the OpenR/C Truggy.
For the electronics i got myself a DJI 450 Flamewheel and basically took all the electronics from it to use in my own design.
As i never got to fly it myself a few other have 3D Printed and built their own.
