When you buy an IMU from a manufacturer, it provides the guidelines on how to read this sensor (IMU). For clarification, IMUs only provide linear accelerations, not the rotational ones. Rotational velocities are obtained from the gyroscope embedded inside an IMU. These velocities are then integrated to obtain the orientation. Some IMUs come with a ...

Most quadcopters position the flight controller/sensors at the center with the battery slightly above or below but still on the center. If you are planning on building a race quad that will not use auto level, then you can place your gyro anywhere as the roll rate will be measured the same (just ensure that you set the orientation parameter properly in its ...

If you ran the setup with servo tester, connection between motor and ESC is fine. Therefore, check with oscilloscope if your Arduino generates proper signal. Typically, ESCs proper input is 50Hz PWM with 1000-2000us duty. Ensure, that you have these values correctly. Moreover, ensure that high and low voltage levels are correct - 5V/3.3V (depending on ...

Firstly inspect propellers for damage, followed by motor assembly, and finally to reduce vibration on electronics use double sided tape. The other problem I see in the picture is the breadboard. By soldering your components onto a PCB you'll reduce vibration slightly. I had a similar problem with my rocket, so I soldered my wires and sensors to a PCB.
