RC Stick calibration?

[scro]

I recently had a popup appear on my RC (the "DJI RC" with the built in screen and built in antennas) stating it needed a stick calibration. I went into the menu and started the calibration process, but it seems to just get stuck on the step where it asks you to move the sticks and wheels through their full range of motion, and it never seems to move onto the next step. All the controls seem to go to +/- 100% except for the left stick which tops out at around +70% on the side-to-side axis (ie yaw).

Any ideas why it doesn't complete the calibration?

I don't have any obvious magnetic objects (eg watch, bracelets, ferrous objects etc) nearby that may hinder the process.

Check the following:
Is the drone turned off? it needs to be.
Is your firmware up to date? check.
Are you sure you are using FULL MOVEMENTS? (not missing any icons).
Use slow steady movements on the controller. It helps sometimes to put the controller down on a flat surface.
The most common reason for the problem you have is.......Electromagnetic interference......Take your calibrating outside. concrete will cause problems.
Keep us posted !

Thanks for the reply @Cafguy Some good points, a few of which I didn't explicitly check before trying to calibrate but, looking back, I'm confident I'm good on all these points. I've done RC controller calibrations often enough before on other systems, but just not on the DJI RC. I wonder if the calibration was expecting a higher stick output than ~70% to register as full range movement on that axis? There was definitely full physical movement of the stick, but the hall sensor output was less than expected (probably hence the flag for calibrating).

edit - I'm sure it's what you mean when you say "concrete will cause problems" but the concrete itself isn't really a problem, rather the ferrous reinforcing very often hidden embedded in the concrete, which can mess up compass readings, and in this case influence the hall sensor outputs.
