The motors will not shut down even in the CSC stick position. The remote, IMU, and compass have all been recalibrated numerous times to no avail.
AC Firmware has been rolled back to V1.8 and RC to V1.6 still the problem persists. Currently shutting off the battery on the AC is the only way to kill the motors when they have spun up. With the props on, it shuts down just fine however, I'm too scared to fly it with this being to only inspire I have that does this.
I beginning to think this is either an ESC or FC issue, it seems as if all the ESC's or flight controller has lost the ESC's calibration.
I have ordered new V2 motors with ESCs as I don't know of anything else to try at this point.
Update - I replaced the Ncore with a brand new one fresh out of the box and still that didn’t resolve this issue. I can only hope the new motors with esc’s fixes this.
As far as history on this I1... I acquired this Pro from a friend who had crashed it badly into a tree and then got it repaired under warranty by a Dji retailer that is now no longer in business. I’m suspecting now they really did something wrong to this I1 because it was repaired with the V1 arms as I remember my friend telling me at the time there was no V2 arms available for it when it was repaired.
