That servo is likely pulling too much power for the ESC you have.... The cheapest options would be a capacitor or an external BEC. There is a note on that servo:

external BEC, or
BEC stabilizing receiver capacitor may be needed for efficient, glitch free operation in low voltage electric applications.
