I put it in the last message also
Here it is again.
"Do you have any spare InfinityM (not P3) top (YAW) mounts?"

You should plan a Gimbal version with installed encoders!
I think its the technique we need and there are so far no available gimbals on the market!
I think these additional sensor will kill many of the problem we have on brushless gimbals. ...
On the market right now there are at least 5 Brushless Gimbals that have encoders in their motors:
Freefly Systems' MōVI M10, MōVI M5 & MōVI M15
DJI Global's RONIN, Zenmuse
ACR Systems' The Beast (previously known as BeSteady FOUR)
Prevents motors from losing synchronization and skipping steps.
Provides the information about frame angle and angle of the camera relative to frame, that can be important for some kind of applications.
For many cases it can significantly decrease power consumption by using field-oriented control strategy to drive motors.
Increases instant torque in the same way.
Allows the controller to get information about the camera balance for automatic balancing (with help of extra DC servo motors and moving counterweights).
The firmware also retains an option to adjust camera position by hands.
Increases the precision of stabilization by applying FOC-specific compensations.
List of supported encoders
AMT203 – absolute (capacitive technology) 12bit, SPI communication
AS5048A,B – absolute (magnetic) 14bit, PWM, I2C or SPI communication, not assembled.
MA3 – absolute (magnetic) 10-12bit, assembled. PWM communication.
Analog – potentiometer or any other type where analog output is proportional to angle
AS5600** – absolute magnetic encoder with Analog or PWM interface

I was playing a lot with encoders while working with BeSteady (ACR), a lot ealier than they was announced by basecam...
For now I am not convinced to use them, but maybe soon, we will see...
For sure they are complex and difficult to set for user.

InfinityMR is already in preorder:
First videos are coming next week.
