Hi john-boy to reset GM esc you have to do the following:
1.Turn on transmiter then receiver as normal
2.Press and hold button on esc untill it bleeps three times then release
3.Press and hold button on esc again untill bleeps two times then release
4.Turn off then turn back on receiver and all being well your esc should be set back to factory default settings

If you need any more help let me know as i use GM 90 motor and still have manual for it.
