CoolCopter

Used to start with facebook at the morning... it's replaced by Generate. Very cool software. I wish i was half of my age. What tools do young engineers today have to amuze themselves in the cad world... (I draw my first five years with ink and paper... and then appeared a 2D cad station, wow) I made my design on base of this generated process: https://generate-de.frustum.com/#/workspace/1132/scenario/3253 11.74 gramm When i hear motor i think on torque... and it was a personal challenge to translate it to Generate software, i think i managed (and easy). Placed the motors in CW and CCW positions. (Found out that it seems common on the quadcopters concept) Also enough space for the "adhesive backed velcro" for the different components and enough clearance for the M2 bolts. Even managed to get holes for the circlips and axl end from the motor. The force from the motors is token higher (6N in place of 4.6N), i think their will be some wind to lift these hughe propellers to higher levels... Also have other processes with nominal torque: https://generate-de.frustum.com/#/workspace/1132/scenario/3169 13.49 gramm https://generate-de.frustum.com/#/workspace/1132/scenario/3244 11.72 gramm https://generate-de.frustum.com/#/workspace/1132/scenario/3255 9.79 gramm I post the lightest and my favorite, the 11.74 gramm. (Generate generated a bridge under the electronics, looks cool ;-) Guess you can go lower, but think the biggest forces will come from human manipulating and i do not thrust the thin printing.
