In the meantime, will upgrading to 508 firmware solve the sensor issues on my Justock? Just want to know since I don't have the programming box but I may give it a shot.
The sensor port had been fixed with the 508 zero timing v3 version a very long time ago which was to sensitive with some motors like the lrp etc .now you might want to have a look at your motor and the sensor board in that motor you might have some damaged hall sensors even one can cause an issue as it will send back a distorted signal back to the esc .
