You know a good engineer works to balance the design requirements and practical implementation. Drones use the mpu9250 extensively and they have to do minute rapid control loops to control a craft moving fast in 3 full dimensions. They work fine. You are talking about a craft that lumbers along slowly in comparison. Why would you need 1000hz control loops?
You seem not to be considering the simply adequate solution for the problem which is always the best engineering choice. Cheap and reliable.
We have developed and running a PID system with control at 1ms, although not for this application.
It is for another application that required the maximum precision and smoothness in the movement and at the same time enough power.
What do we start from this proven development and of course we will adapt the times.
