i've had max 8 do that too me but i didn't have cap pack's insatlled for 6s. If that help's.Perhaps it's my fault for buying an RTR hobbywing ESC from aliexpress. Perhaps it's just bum luck. It was running in my mt410, so its not like it was working very hard.
Would you be concerned with buying another from aliexpress? Would you get another max8 but from a "reputable" seller? Would you switch it up and try something else?
Im usually a "jump right back up on the horse when I fall" kind if person. But I've got a limited budget and had very recently purchased this max8, so I'm a bit sour.
