Default Esc keeps going into sensorless mode! please help

for the last 4 weeks ive been running my hobbywing xerun 2.0 60 amp speedo with a duo 2 10.5 motor . i have an intermittent fault where the esc goes into sensorless mode during the 5 min run . ive changed the sensor board and the cable , but it still does it .
anyone got any ideas ,only seems to happen when running more than 30 boost ,hobby wing say this esc can run down to a 5.5 motor

give us your full setup, fdr and after how many minutes does it go into sensorless?

Did you try to reload the software or update it?

Between the esc and the motor there is to much timing. either take timing from the motor or from the esc.

i would recommend going to the hobbywing thread, but as far as i remember, this was always a problem with the software being to narrow in the sensortiming. and with some motors the esc looses the rotor position then and switches into sensorless mode. i think in the hobbywing thread cobra posted a updated 211 software with is less narrow on the sensors so it should work with really any motor.

Try zero timing on the motor. if that solves the problem. I had the same problem with a D2 with two different esc from two different manufacturers.

I changed motors and no more probelm.
