altHold freq in firmware only 100Hz

Re: Smooth perpendicular lifting

Thanks for the answers! I changed the initial position of the quadro from ground to ~50cm higher and it worked better, the lifting was more vertical. What I didn't manage to do is make it stay there or at least lower it gentle. I used your thing with 2 sec - 60% ; 1 sec - 30% ; 3 sec - 45% and vario...

Smooth perpendicular lifting

Hi, I am at the beggining of my experience with crazyflie 2.0 so sorry if my questions sound dumb. How can I achieve a vertical (perpendicular) lift of the quadcopter? I've used the ramp.py example to modify thrust, but when it gets too big the quadcopter goes in a particular direction (i.e. left or...
