Good Evening,
At the beginning thanks to all for yours work.
I've buyed a crazyflie and now it is arrived to my home (Yeah!!!) but i noticed that when i increase the thrust the drone hangs towards motor 1.
So can someone help me resolving this problem or to understand it?
(I think is a PID problem).
Thanks to all

Hi,

Does it hang as well when the copter is hovering? If so it could just be the accelerometer calibration that is a bit off. You can trim it in the GUI and you can write trimming values in the copter using the bootloader and config block.

If it is only drifts when accelerating try to check the propeller maybe exchanging it. Have a look at the motor as well to see if nothing is stuck in the axis or if there is no damage on the motor housing.

I doubt it is the PID.

Thanks for the reply,
I've tested your solution and it works .
Do you know some methods to measure the motors's power?

Hi,

Nice to hear that you solved it!

We have measured the motor power at some point but I am not sure how it was done, Tobias knows but he is now in vacation...

Anyway, there is no electronic on the Crazyflie to measure the electric power consumed by the motors, so this measurement was done off-line.
