Re: Crazyflie wants to flip from take-off, unstable in hover
I tried the alternative parameters suggested, and also tried taking off from the corner of a table (which appeared to reduce the ground effects some). However I'm still struggling greatly to maintain a reasonable hover. My point of comparison is controlling other RC electric helicopters with counter...

Re: Crazyflie wants to flip from take-off, unstable in hover
Indeed the 'at rest' values were off a little. I was able to trim them out using the UI to get roll & pitch to zero - it's still difficult to fly, it's very prone to drifting quickly - but it's not 'flipping' anymore. One problem is keeping the 'front' consistent. From the perspective of roll &a...

Re: Crazyflie wants to flip from take-off, unstable in hover
Thanks for the quick responses! The client shows a stable artificial horizon when the quadcopter is on the floor etc. There's a bit of change in the Yaw value - but it's less than 1 degree per second (perhaps 0.3-0.5 degrees per second). If I give it some extra thrust to try and overcome ground effe...

Re: Crazyflie wants to flip from take-off, unstable in hover
I added a photo of the connections on the reverse : https://www.dropbox.com/sc/jgitoea5dmms9ia/my0gmItXiv I think the connections for M3/M4 are correct - The only thing that strikes me as slightly 'odd' is that from a wiring length/layout perspective M4's solder pads are closer to M3's mount - so M4...

Crazyflie wants to flip from take-off, unstable in hover
My crazyflie flips from takeoff, if I suspend it from a bit of string and apply thrust whilst it generally stays level it will veer off in one direction or another. I've double checked both the prop order and orientation and the wiring (see photos in album below). There doesn't appear to be any hair...

Constantly changing Yaw value and unstable flight
I've just finished assembling my CrazyFlie and am trying to fly it for the first time. It seems to want to always flip or turn over immediately after takeoff. I've checked the motor rotations and propellor configurations and as far as i can tell they're correct. 1 & 3 rotate CCW and 2 & 4 ro...
