RE: Karbonite gears
Point-
If your refering to hitec 635 servos,I use them in some of my planes.I never had a problem.Some guys say the main hub breaks off.I was told that if you use loctite on the screw it reacts with the karbonite.I don't know.You really have to see what actually these guys are using them on.If it was that big of an issue,Hitec would pull them.My 2 cents.
