"For high stability you want the autopilot with the lower noise IMU gyros. The Pixhawk 1 with the lower noise MPU6000 IMU gyros is a better autopilot for hexacopter stability. The Pixhawk 1 uses the same processor…"
"That ICM20602 looks great. Both the ICM20600 and the ICM20602 have rate noise power spectral intensity of 0.004 deg/sec/root(Hz). This is slightly less noise than the MPU6000's 0.005 deg/sec/root(Hz) and much less than…"
"The Pixhawk2.1 is an well designed autopilot. Not sure why the lower performance IMU was used. Only one MPU9250 IMU is on the isolated IMU board. The ICM20600 IMU could have been used and it is slightly…"
"The Pixhawk1(2.4.x) uses the MPU6000 IMU, a redundant set of gyros(L3GD20 3-axis 16-bit gyroscope) and accelerometers(ST Micro LSM303D 3-axis 14-bit accelerometer / magnetometer). The MPU6000 IMU gyro noise(0.005 deg/sec/root(Hz)…"
"Not sure why you would want to use the ICM-20608 IMU in a new autopiliot. It is a poor IMU compared to the MPU6000 used in the Pixhawk and even the APM autopilot.
The ICM-20608 being used in the Pixhawk3 has noisier gyros than the…"
"Tim, The Krytox oils are pretty amazing. They are what makes the Krytox grease work. Krytox GPL103 might not be too viscous at low temperatures and has a low vapor pressure. I think you can get small…"
That looks about right. You will want to put all the components, camera, battery, wings, tail, pixhawk etc on a balance board. That way you can experiment and find the locations that put the CG at the wing spar…"
"Hi Vincent, Great to hear you have the bixler 3 flying. Putting cameras in the belly under the wing works for me. To open up the center section you may want to move the tail servos back to get the push rods…"
