Personally i would pick up the castle 20amp.. but that black one should work. The blue is only 5amp max. I would pick up the black one. Do you have the specs on them both or the link to them. Will check into them more for ya bud
Need to get a bec for that servo. Or a direct connection to its own lipo. The 1080 should have a 7.4v max bec in it. What else is plugged into esc?? The servo is probably pulling much power. Sending the esc into over load putting into safety shut off..
