You know what kind of pees me off is along with the e mail from Hi tec telling me that the karb servos are not recommended for gassers was a legal notice warning me not to reprint the email and show it to anybody...I think that is just Bull S.....Its no wonder nobody know much about it..Anything you read on the box looks good..I thought they were better than anything but titanum..If it had dent been for you guys giving me a heads up I never would have knowen..
My big question is why are they still using that gear train. They don't stand up to vibration and planes with large controls even in 60 size planes and using glow engines get vibration and have sudden hard landings that will shear the gears. If I would have known about them not to be used on gas powered planes and large scale I would have bought different models of servos, still Hitec but with a different gear train. I would have to go look at the numbers but I bought the cheap standard size I think 67 in. lb. digitals with the Karb gears when they first came out. I have had great luck with them but on 60 size IMAC and Pattern planes. I would rather have nylon the the Karbonite gears.
They still use the gear train and advertise them as something special without any warning at all or advise on plane size or engine type. GHo figure??
