Forgot to mention that I have the DS 8231 on rudder. 88 oz. in. with the same additional 20% on 6V. I like metal gears in the right situation. The DS811's are 1.44 oz. each and the 8231 is 1.73 oz. Not bad weights when considering what they do. Most MG's start @ 2 oz. each. I have JR 8411 MG's on the Extra. Silly power but weigh 2.10 oz. each. So on a .60 size plane with five servos, not counting throttle, do you want to put 10+ oz. of servo in it? If it comes out @ 8 lbs. or lighter and you have em, use em. Joe
