WTF is up with my MGM80

[sleepy23]

ok, heres the deal, running the mgm80 with feigao 6s in a t4 with a jr x3s pro radio. I have two big issues:

1. when the pack starts to fade, the esc looses its mind and starts driving in reverse. at first i thought it was cuz of the pack i was running, but then i ran it today and it did it again with a race quality pack.

2. it has basically been impossible for me to get my esc programmed based on the guide i got from the link on here. i can get into the programming stage, but then when i follow the steps, i never get the same beeps as i am suppose to.

any help on these two questions would be greatly appreciated as now i am wishing i would have spent the extra 30 bucks for the warrior 9918
