Hello Marcus, I like your thought, set the current "Emergency Stop" to On, requiring "Arm" button press before thrust can be applied. That would be a significant improvement and one that could rapidly be deployed if connection is lost during flight. Even so, if you pick up the co...

Seems like a potential safety issue. On connect, why should a non-null value for thrust be permitted? On connection, wouldn't it be better to zero the value and throw a warning to the user before allowing a fly-away? Or even some kind of general "safety interlock" on the controller to ensu...

Congratulations on the volume of posts! We're all glad to see this level of participation, I'm sure. I believe you've answered my question. An advanced Crazyflie would be a complete re-design of the board and that offers an opportunity for new features. It doesn't seem like a LQFP48 would be practic...

Regarding the future, any thoughts relative to updating the MCU to the binary-compatable STM32F4*? I wonder if it would not make a direct interface to a nano digital video camera, and related processing/transfer of images via Crazyradio, a somewhat more practical. Just wondering if there's any think...

If the port never worked, why not get a replacement board? Would be easier. Payload weight would be reduced for tricopter!

I agree that the dart solution is good for protecting the bottom of the motors.

The frames described above also encompass the motor bottoms but additionally protect the rotors from damage in the X-Y plane of the Crazyflie. Some of the newer designs also protect the top 'flie.

Yes, designs over a few grams are going to be too heavy. A tough problem.

I think I've realized that the greatest risk of damage to the Crazyflie in a crash is that contact between the edges of the pcb and motor cans. After many crashes and manual deformations to try to remove dents, I've had to replace 2 motors from that so far. Those repairs put the main board at risk g...

I agree with foosel. Adding deadzone e. Even a slight dent in the motor case can affect motor performance in a big way.
