I'm doing my first big quadcopter using crazyflie to control:

airframe ESC and brush-less motors propeller assembly drawing crazyflie for control

Looks nice! To reduce vibrations you might not want to strip it down directly to the frame, but but some softer foam in between. Keep us posted when it's flying!

Yes, I planed to use rubber washer between motor and frame.
But the other guys said to me, it's not so necessary to do this for this size quadcopter.
I also believe it's better to have.

But firstly, I need setup the balance testing environment and let it fly. Then I can do other optimizations.
I will keep update.

Hello wwfiney ! I will do the same. Pls post your evolution for us ! Sucess in your project.

Hi, i have three questions about your setup.

According to this post http://www.bitcraze.se/2014/03/brushles ... crazyflie/

Is not necessary the resistors to reduce the voltage to 2.8v from ESC's ?

And about the brushless driver tag activation on code do you did ?

The ESC's have simonK firmware compatible ?

1 I didn't connect ESC's 5V to crazyflie power input. I connect it to USB input, USB is 5V, so it's OK. (tradeoff is you cannot get correct battery power status)
2 I didn't use the the code of crazyflie-firmware for brushless motor, I write it myself. You can reference the code https://github.com/wwfiney/crazyflie-fi ... tree/snake, my project is the "snake" branch

Thanks for reply ! Great evolution, i will see your video now !
