Pat thanks for the info. I have a JR 811 that came with my radio. The speed is .18sec/60 deg. @ 4.8v (can't find speed for 6.0v), would this be fast enough or would you recommend something faster? The Hitec 425bb is .21sec/60 deg. @4.8v and .16sec/60 deg @6.0v. I thought about lithions but the added cost for the batteries + regulators + new chargers didn't add up well. On top of that I here they are not real user friendly (charging wise) and they can catch fire easily. I have been told the weight you save on the battery you lose when you add the regulators. The ringing I was refering to is with the servo not hooked up to anything. I just have them sitting on the bench (no control surfaces hooked up). Is the ringing in this condition normal?

Thanks again
