Phantom 4 has dual IMU's and dual Compasses.

As for peace of mind, I feel this feature is by far the one the best upgrades to the P4.

I wonder how this will work???
If you wear 2 watches on 1 hand and set them the same time and then goto another country, both your watches are still going to be wrong. In other words, how do we calibrate them if both get calibrated incorrectly??
Unless they are 2 different variants - eg an analogue and digital as 1 so erroneous ambiguous data can be eliminated.

I'm going to guess that if the calibration is correct, then readings on the two redundant devices will be very close. But if the calibration is incorrect, the readings will more likely be further apart indicating a problem.

You figure it's for redundancy right?? Jet airplanes have two of everything when it comes to the important electronics but you're right. It's interesting how such a system will work on a little quadcopter like this. For instance, when you calibrate, will both systems be calibrated at the same time or will they be independent of each other?

They have 3. Much easier to determine who is wrong with 3.
