Default Current draw for sail serv?

I have a 2 channel surface radio set for my RC sailboat. I have notice lately considerable radio problems, specifically control of either servo comes and goes. I connected an analog meter in the positive battery wire, the meter I think reads to 250 mA. The rudder servo moves the needle about 1/3 the scale when actuated, the sail servo pegs the meter. Is this enough info to tell if the problem is the servo? A charged, this AM, new 4.8v battery was almost in the red after only about 15 minutes use.

What servo are you using for the sail?

Should have mentioned that! It's an 815BB.

Yeah that servo is a current hog. When moving without being connected, it will draw about 800mA. Hitec suggests using the included y-harness to bypass the BEC function of the receiver and I suggest about a 1400mA battery pack or more.
