Well i called the futaba service center again this morning and talked to a different guy, who was very polite and seemed willing to help. I told him yesterday i was told i could only run NIMH batteries on futaba servos not lipos or life batteries. I told the service center guy a lot of people are running LIFE batteries and no reg. with no problems. He told me to hold he would check. When he came back he said i would be fine using a LIFE battery set up without a regulator. So that is what i am going to do.
