Ehab, is 6985 or 5985. I just got 4 HS-5985MG and they are the same specs as yours. 144 oz.in @ 4.8v and 172 oz.in @6v. They said have 3 metal gears and one karbonite, not sure wich gear is the karbonite. I'm planning to use them in my new pst panther for ail, elv. and rudd.

So it looks like it will not be a good servo for jets? Only a few years ago we were flying turbine Bandits and other jets with servos with plasic gears...
